Determiner phrase

Last updated

In linguistics, a determiner phrase (DP) is a type of phrase headed by a determiner such as many. [1] Controversially, many approaches take a phrase like not very many apples to be a DP, headed, in this case, by the determiner many. This is called the DP analysis or the DP hypothesis. Others reject this analysis in favor of the more traditional NP (noun phrase or nominal phrase) analysis where apples would be the head of the phrase in which the DP not very many is merely a dependent. Thus, there are competing analyses concerning heads and dependents in nominal groups. [2] The DP analysis developed in the late 1970s and early 1980s, [3] and it is the majority view in generative grammar today. [4]

The competing analyses

Although the DP analysis is the dominant view in generative grammar, most other grammar theories reject the idea. For instance, representational phrase structure grammars follow the NP analysis, e.g. Head-driven Phrase Structure Grammar, and most dependency grammars such as Meaning-Text Theory, Functional Generative Description, and Lexicase Grammar also assume the traditional NP analysis of noun phrases, Word Grammar being the one exception. [1] Construction Grammar and Role and Reference Grammar also assume NP instead of DP. Noam Chomsky, on whose framework most generative grammar has been built, said in a 2020 lecture,

I’m going to assume here that nominal phrases are actually NPs. The DP hypothesis, which is widely accepted, was very fruitful, leading to a lot of interesting work; but I’ve never really been convinced by it. I think these structures are fundamentally nominal phrases. [. . . ] As far as determiners are concerned, like say that, I suspect that they are adjuncts. So I’ll be assuming that the core system is basically nominal. [5]

The point at issue concerns the hierarchical status of determiners. Various types of determiners in English are summarized in the following table.

ArticleQuantifierDemonstrativePossessive
a/an, theall, every, many, each, etc.this, that, those, etc.my, your, her, its, their, etc.

Should the determiner in phrases such as the car and those ideas be construed as the head of or as a dependent in the phrase? The following trees illustrate the competing analyses, DP vs. NP. The two possibilities are illustrated first using dependency-based structures (of dependency grammars):

DP vs. NP 5 DP vs. NP 5.png
DP vs. NP 5

The a-examples show the determiners dominating the nouns, and the b-examples reverse the relationship, since the nouns dominate the determiners. The same distinction is illustrated next using constituency-based trees (of phrase structure grammars), which are equivalent to the above:

DP vs. NP 6 DP vs. NP 6.png
DP vs. NP 6

The convention used here employs the words themselves as the labels on the nodes in the structure. Whether a dependency-based or constituency-based approach to syntax is employed, the issue is which word is the head over the other.

Arguments for DP over NP

The DP-hypothesis is held for four main reasons: 1) facilitates viewing phrases and clauses as structurally parallel, 2) accounts for determiners often introducing phrases and their fixed position within phrases, 3) accounts for possessive -s constructions, and 4) accounts for the behaviour of definite pronouns given their complementary distribution with determiners.

Parallel structures

The original motivation for the DP-analysis came in the form of parallelism across phrase and clause. The DP-analysis provides a basis for viewing clauses and phrases as structurally parallel. [6] The basic insight runs along the following lines: since clauses have functional categories above lexical categories, noun phrases should do the same. The traditional NP-analysis has the drawback that it positions the determiner, which is often a pure function word, below the lexical noun, which is usually a full content word. The traditional NP-analysis is therefore unlike the analysis of clauses, which positions the functional categories as heads over the lexical categories. The point is illustrated by drawing a parallel to the analysis of auxiliary verbs. Given a combination such as will understand, one views the modal auxiliary verb will, a function word, as head over the main verb understand, a content word. Extending this type of analysis to a phrase like the car, the determiner the, a function word, should be head over car, a content word. In so doing, the NP the car becomes a DP. The point is illustrated with simple dependency-based hierarchies:

NP vs. DP 1.1 NP vs. DP 1.1.png
NP vs. DP 1.1

Only the DP-analysis shown in c establishes the parallelism with the verb chain. It enables one to assume that the architecture of syntactic structure is principled; functional categories (function words) consistently appear above lexical categories (content words) in phrases and clauses. This unity of the architecture of syntactic structure is perhaps the strongest argument in favor of the DP-analysis.

Position

The fact that determiners typically introduce the phrases in which they appear is also viewed as support for the DP-analysis. One points to the fact that when more than one attributive adjective appears, their order is somewhat flexible, e.g. an old friendly dog vs. a friendly old dog. The position of the determiner, in contrast, is fixed; it has to introduce the phrase, e.g. *friendly an old dog, *old friendly a dog, etc. The fact that the determiner's position at the left-most periphery of the phrase is set is taken as an indication that it is the head of the phrase. The reasoning assumes that the architecture of phrases is robust if the position of the head is fixed. The flexibility of order for attributive adjectives is taken as evidence that they are indeed dependents of the noun.

Possessive -s in English

Possessive -s constructions in English are often produced as evidence in favor of the DP-analysis. [7] The key trait of the possessive -s construction is that the -s can attach to the right periphery of a phrase. This fact means that -s is not a suffix (since suffixes attach to words, not phrases). Further, the possessive -s construction has the same distribution as determiners, which means that it has determiner status. The assumption is therefore that possessive -s heads the entire DP, e.g.

  1. [the guy with a hat]'s dog
  2. [the girl who was laughing]'s scarf

The phrasal nature of the possessive -s constructions like these is easy to accommodate on a DP-analysis. The possessive -s heads the possessive phrase; the phrase that immediately precedes the -s (in brackets) is in specifier position, and the noun that follows the -s is the complement. The claim is that the NP-analysis is challenged by this construction because it does not make a syntactic category available for the analysis of -s, that is, the NP-analysis does not have a clear means at its disposal to grant -s the status of determiner. This claim is debatable, however, since nothing prevents the NP-analysis from also granting -s the status of determiner. The NP-analysis is however forced to acknowledge that DPs do in fact exist, since possessive -s constructions have to be acknowledged as phrases headed by the determiner -s. A certain type of DP definitely exists, namely one that has -s as its head.

Definite pronouns

The fact that definite pronouns are in complementary distribution with determiners is taken as evidence in favor of DP. [8] The important observation in this area is that definite pronouns cannot appear together with a determiner like the or a in one and the same DP, e.g.

  1. they
  2. *the they
  1. him
  2. *a him

On a DP-analysis, this trait of definite pronouns is relatively easy to account for. If definite pronouns are actually determiners, then it makes sense that they should not be able to appear together with another determiner since the two would be competing for the same syntactic position in the hierarchy of structure. On an NP-analysis in contrast, there is no obvious reason why a combination of the two would not be possible. In other words, the NP-analysis has to reach to additional stipulations to account for the fact that combinations like *the them are impossible. A difficulty with this reasoning, however, is posed by indefinite pronouns (one, few, many), which can easily appear together with a determiner, e.g. the old one. The DP-analysis must therefore draw a distinction between definite and indefinite pronouns, whereby definite pronouns are classified as determiners, but indefinite pronouns as nouns.

Arguments for NP over DP

While the DP-hypothesis has largely replaced the traditional NP analysis in generative grammar, it is generally not held among advocates of other frameworks, for six reasons: [9] 1) absent determiners, 2) morphological dependencies, 3) semantic and syntactic parallelism, 4) idiomatic expressions, 5) left-branch phenomena, and 6) genitives.

Absent determiners

Many languages lack the equivalents of the English definite and indefinite articles, e.g. the Slavic languages. Thus in these languages, determiners appear much less often than in English, where the definite article the and the indefinite article a are frequent. What this means for the DP-analysis is that null determiners are a common occurrence in these languages. In other words, the DP-analysis must posit the frequent occurrence of null determiners in order to remain consistent about its analysis of DPs. DPs that lack an overt determiner actually involve a covert determiner in some sense. The problem is evident in English as well, where mass nouns can appear with or without a determiner, e.g. milk vs. the milk, water vs. the water. Plural nouns can also appear with or without a determiner, e.g. books vs. the books, ideas vs. the ideas, etc. Since nouns that lack an overt determiner have the same basic distribution as nouns with a determiner, the DP-analysis should, if it wants to be consistent, posit the existence of a null determiner every time an overt determiner is absent. The traditional NP analysis is not confronted with this necessity, since for it, the noun is the head of the noun phrase regardless of whether a determiner is or is not present. Thus the traditional NP analysis requires less of the theoretical apparatus, since it does not need all those null determiners, the existence of which is non-falsifiable. Other things being equal, less is better according to Occam's Razor.

Morphological dependencies

The NP-analysis is consistent with intuition in the area of morphological dependencies. Semantic and grammatical features of the noun influence the choice and morphological form of the determiner, not vice versa. Consider grammatical gender of nouns in a language like German, e.g. Tisch 'table' is masculine (der Tisch), Haus 'house' is neuter (das Haus), Zeit 'time' is feminine (die Zeit). The grammatical gender of a noun is an inherent trait of the noun, whereas the form of the determiner varies according to this trait of the noun. In other words, the noun is influencing the choice and form of the determiner, not vice versa. In English, this state of affairs is visible in the area of grammatical number, for instance with the opposition between singular this and that and plural these and those. Since the NP-analysis positions the noun above the determiner, the influence of the noun on the choice and form of the determiner is intuitively clear: the head noun is influencing the dependent determiner. The DP-analysis, in contrast, is unintuitive because it necessitates that one view the dependent noun as influencing the choice and form of the head determiner.

Semantic and structural parallelism

Despite what was stated above about parallelism across clause and DP, the traditional NP-analysis of noun phrases actually maintains parallelism in a way that is destroyed if one assumes DPs. The semantic parallelism that can be obtained across clause and NP, e.g. He loves water vs. his love of water, is no longer present in the structure if one assumes DPs. The point is illustrated here first with dependency trees:

DP vs. NP 3 DP vs. NP 3.png
DP vs. NP 3

On the NP-analysis, his is a dependent of love in the same way that he is a dependent of loves. The result is that the NP his love of water and the clause He loves water are mostly parallel in structure, which seems correct given the semantic parallelism across the two. In contrast, the DP analysis destroys the parallelism, since his becomes head over love. The same point is true for a constituency-based analysis:

DP vs. NP 4 DP vs. NP 4.png
DP vs. NP 4

These trees again employ the convention whereby the words themselves are used as the node labels. The NP-analysis maintains the parallelism because the determiner his appears as specifier in the NP headed by love in the same way that he appears as specifier in the clause headed by loves. In contrast, the DP analysis destroys this parallelism because his no longer appears as a specifier in the NP, but rather as head over the noun.

Idiomatic meaning

The fixed words of many idioms in natural language include the noun of a noun phrase at the same time that they exclude the determiner. [10] This is particularly true of many idioms in English that require the presence of a possessor that is not a fixed part of the idiom, e.g. take X's time, pull X's leg, dance on X's grave, step on X's toes, etc. While the presence of the Xs in these idioms is required, the X argument itself is not fixed, e.g. pull his/her/their/John's leg. What this means is that the possessor is NOT part of the idiom; it is outside of the idiom. This fact is a problem for the DP-analysis because it means that the fixed words of the idiom are interrupted in the vertical dimension. That is, the hierarchical arrangement of the fixed words is interrupted by the possessor, which is not part of the idiom. The traditional NP-analysis is not confronted with this problem, since the possessor appears below the noun. The point is clearly visible in dependency-based structures:

DP vs. NP 2 DP vs. NP 2.png
DP vs. NP 2

The arrangement of the words in the vertical dimension is what is important. The fixed words of the idiom (in blue) are top-down continuous on the NP-analysis (they form a catena), whereas this continuity is destroyed on the DP-analysis, where the possessor (in green) intervenes. Therefore the NP-analysis allows one to construe idioms as chains of words, whereas on the DP-analysis, one cannot make this assumption. On the DP-analysis, the fixed words of many idioms really cannot be viewed as discernible units of syntax in any way.

Left branches

In English and many closely related languages, constituents on left branches underneath nouns cannot be separated from their nouns. Long-distance dependencies are impossible between a noun and the constituents that normally appear on left branches underneath the noun. This fact is addressed in terms of the Left Branch Condition. [11] Determiners and attributive adjectives are typical "left-branch constituents". The observation is illustrated with examples of topicalization and wh-fronting:

(1a) Fred has helpful friends. (1b) *...and helpful Fred has friends.- The attributive adjective helpful cannot be topicalized away from its head friends.
(2a) Sam is waiting for the second train.  (2b) *...and second Sam is waiting for the train.- The attributive adjective second cannot be topicalized away from its head train.
(3a) Susan has our car. (3b) *Whose does Susan have car?- The interrogative determiner whose cannot be wh-fronted away from its head car.
(4a) Sam is waiting for the second train. (4b) *Which is Sam waiting for train?- The interrogative determiner which cannot be wh-fronted away from its head train.

These examples illustrate that with respect to the long-distance dependencies of topicalization and wh-fronting, determiners behave like attributive adjectives. Both cannot be separated from their head noun. The NP-analysis is consistent with this observation because it positions both attributive adjectives and determiners as left-branch dependents of nouns. On a DP-analysis, however, determiners are no longer on left branches underneath nouns. In other words, the traditional NP-analysis is consistent with the fact that determiners behave just like attributive adjectives with respect to long-distance dependencies, whereas the DP-analysis cannot appeal to left branches to account for this behavior because on the DP-analysis, the determiner is no longer on a left branch underneath the noun.

Genitives

The NP-analysis is consistent with the observation that genitive case in languages like German can have the option to appear before or after the noun, whereby the meaning remains largely the same, as illustrated with the following examples:

a. das Haus meines Bruders 'the house of.my brother'
b. meines Bruders Haus 'my brother's house'
a. die Arbeit seines Onkels 'the work of.his uncle'
b. seines Onkels Arbeit 'his uncle's work'

While the b-phrases are somewhat archaic, they still occur on occasion in elevated registers. The fact that the genitive NPs meines Bruders and seines Onkels can precede or follow the noun is telling, since it suggests that the hierarchical analysis of the two variants should be similar in a way that accommodates the almost synonymous meanings. On the NP-analysis, these data are not a problem because in both cases, the genitive expression is a dependent of the noun. The DP-analysis, in contrast, is challenged because in the b-variants, it takes the genitive expression to be head over the noun. In other words, the DP-analysis has to account for the fact that the meaning remains consistent despite the quite different structures across the two variants.

In linguistics, syntax is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). There are numerous approaches to syntax that differ in their central assumptions and goals.

In grammar, a noun is a word that represents a concrete or abstract thing, such as living creatures, places, actions, qualities, states of existence, and ideas. A noun may serve as an object or subject within a phrase, clause, or sentence.

A syntactic category is a syntactic unit that theories of syntax assume. Word classes, largely corresponding to traditional parts of speech, are syntactic categories. In phrase structure grammars, the phrasal categories are also syntactic categories. Dependency grammars, however, do not acknowledge phrasal categories.

In grammar, a phrase—called expression in some contexts—is a group of words or singular word acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. There is a difference between the common use of the term phrase and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as "all rights reserved", "economical with the truth", "kick the bucket", and the like. It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc.. In linguistics, these are known as phrasemes.

In grammar, a part of speech or part-of-speech is a category of words that have similar grammatical properties. Words that are assigned to the same part of speech generally display similar syntactic behavior, sometimes similar morphological behavior in that they undergo inflection for similar properties and even similar semantic behavior. Commonly listed English parts of speech are noun, verb, adjective, adverb, pronoun, preposition, conjunction, interjection, numeral, article, and determiner.

English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.

A noun phrase – or NP or nominal (phrase) – is a phrase that usually has a noun or pronoun as its head, and has the same grammatical functions as a noun. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type.

An adjective phrase is a phrase whose head is an adjective. Almost any grammar or syntax textbook or dictionary of linguistics terminology defines the adjective phrase in a similar way, e.g. Kesner Bland (1996:499), Crystal (1996:9), Greenbaum (1996:288ff.), Haegeman and Guéron (1999:70f.), Brinton (2000:172f.), Jurafsky and Martin (2000:362). The adjective can initiate the phrase, conclude the phrase, or appear in a medial position. The dependents of the head adjective—i.e. the other words and phrases inside the adjective phrase—are typically adverb or prepositional phrases, but they can also be clauses. Adjectives and adjective phrases function in two basic ways, attributively or predicatively. An attributive adjective (phrase) precedes the noun of a noun phrase. A predicative adjective (phrase) follows a linking verb and serves to describe the preceding subject, e.g. The man is very happy.

In linguistics, the head or nucleus of a phrase is the word that determines the syntactic category of that phrase. For example, the head of the noun phrase boiling hot water is the noun water. Analogously, the head of a compound is the stem that determines the semantic category of that compound. For example, the head of the compound noun handbag is bag, since a handbag is a bag, not a hand. The other elements of the phrase or compound modify the head, and are therefore the head's dependents. Headed phrases and compounds are called endocentric, whereas exocentric ("headless") phrases and compounds lack a clear head. Heads are crucial to establishing the direction of branching. Head-initial phrases are right-branching, head-final phrases are left-branching, and head-medial phrases combine left- and right-branching.

In linguistics, branching refers to the shape of the parse trees that represent the structure of sentences. Assuming that the language is being written or transcribed from left to right, parse trees that grow down and to the right are right-branching, and parse trees that grow down and to the left are left-branching. The direction of branching reflects the position of heads in phrases, and in this regard, right-branching structures are head-initial, whereas left-branching structures are head-final. English has both right-branching (head-initial) and left-branching (head-final) structures, although it is more right-branching than left-branching. Some languages such as Japanese and Turkish are almost fully left-branching (head-final). Some languages are mostly right-branching (head-initial).

Dependency grammar (DG) is a class of modern grammatical theories that are all based on the dependency relation and that can be traced back primarily to the work of Lucien Tesnière. Dependency is the notion that linguistic units, e.g. words, are connected to each other by directed links. The (finite) verb is taken to be the structural center of clause structure. All other syntactic units (words) are either directly or indirectly connected to the verb in terms of the directed links, which are called dependencies. Dependency grammar differs from phrase structure grammar in that while it can identify phrases it tends to overlook phrasal nodes. A dependency structure is determined by the relation between a word and its dependents. Dependency structures are flatter than phrase structures in part because they lack a finite verb phrase constituent, and they are thus well suited for the analysis of languages with free word order, such as Czech or Warlpiri.

Possessive determiners are determiners which express possession. Some traditional grammars of English refer to them as possessive adjectives, though they do not have the same syntactic distribution as bona fide adjectives.

<span class="mw-page-title-main">Grammatical relation</span>

In linguistics, grammatical relations are functional relationships between constituents in a clause. The standard examples of grammatical functions from traditional grammar are subject, direct object, and indirect object. In recent times, the syntactic functions, typified by the traditional categories of subject and object, have assumed an important role in linguistic theorizing, within a variety of approaches ranging from generative grammar to functional and cognitive theories. Many modern theories of grammar are likely to acknowledge numerous further types of grammatical relations. The role of grammatical relations in theories of grammar is greatest in dependency grammars, which tend to posit dozens of distinct grammatical relations. Every head-dependent dependency bears a grammatical function.

In linguistics, head directionality is a proposed parameter that classifies languages according to whether they are head-initial or head-final. The head is the element that determines the category of a phrase: for example, in a verb phrase, the head is a verb. Therefore, head initial would be "VO" languages and head final would be "OV" languages.

Determiner, also called determinative, is a term used in some models of grammatical description to describe a word or affix belonging to a class of noun modifiers. A determiner combines with a noun to express its reference. Examples in English include articles, demonstratives, possessives, and quantifiers. Not all languages have determiners, and not all systems of grammatical description recognize them as a distinct category.

<span class="mw-page-title-main">English nouns</span> Part of speech

English nouns form the largest category of words in English, both in the number of different words and how often they are used in typical texts. The three main categories of English nouns are common nouns, proper nouns, and pronouns. A defining feature of English nouns is their ability to inflect for number, as through the plural –s morpheme. English nouns primarily function as the heads of noun phrases, which prototypically function at the clause level as subjects, objects, and predicative complements. These phrases are the only English phrases whose structure includes determinatives and predeterminatives, which add abstract-specifying meaning such as definiteness and proximity. Like nouns in general, English nouns typically denote physical objects, but they also denote actions, characteristics, relations in space, and just about anything at all. Taken all together, these features separate English nouns from other lexical categories such as adjectives and verbs.

Noun ellipsis (N-ellipsis), also noun phrase ellipsis (NPE), is a mechanism that elides, or appears to elide, part of a noun phrase that can be recovered from context. The mechanism occurs in many languages like English, which uses it less than related languages.

<span class="mw-page-title-main">English determiners</span> Determiners in the English language

English determiners are words – such as the, a, each, some, which, this, and numerals such as six – that are most commonly used with nouns to specify their referents. The determiners form a closed lexical category in English.

<span class="mw-page-title-main">English adjectives</span> Adjectives in the English language

English adjectives form a large open category of words in English which, semantically, tend to denote properties such as size, colour, mood, quality, age, etc. with such members as other, big, new, good, different, Cuban, sure, important, and right. Adjectives head adjective phrases, and the most typical members function as modifiers in noun phrases. Most adjectives either inflect for grade or combine with more and most to form comparatives and superlatives. They are characteristically modifiable by very. A large number of the most typical members combine with the suffix -ly to form adverbs. Most adjectives function as complements in verb phrases, and some license complements of their own.
