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.
An adjective is a word that describes or defines a noun or noun phrase. Its semantic role is to change information given by the noun.
An adverb is a word or an expression that generally modifies a verb, adjective, another adverb, determiner, clause, preposition, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how, in what way, when, where, to what extent. This is called the adverbial function and may be performed by single words (adverbs) or by multi-word adverbial phrases and adverbial clauses.
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.
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, function words are words that have little lexical meaning or have ambiguous meaning and express grammatical relationships among other words within a sentence, or specify the attitude or mood of the speaker. They signal the structural relationships that words have to one another and are the glue that holds sentences together. Thus they form important elements in the structures of sentences.
In linguistics, a modifier is an optional element in phrase structure or clause structure which modifies the meaning of another element in the structure. For instance, the adjective "red" acts as a modifier in the noun phrase "red ball", providing extra details about which particular ball is being referred to. Similarly, the adverb "quickly" acts as a modifier in the verb phrase "run quickly". Modification can be considered a high-level domain of the functions of language, on par with predication and reference.
In English grammar, an adverbial is a word or a group of words that modifies or more closely defines the sentence or the verb. Look at the examples below:
A compound is a word composed of more than one free morpheme. The English language, like many others, uses compounds frequently. English compounds may be classified in several ways, such as the word classes or the semantic relationship of their components.
In linguistics, an adverbial phrase ("AdvP") is a multi-word expression operating adverbially: its syntactic function is to modify other expressions, including verbs, adjectives, adverbs, adverbials, and sentences. Adverbial phrases can be divided into two types: complement adverbs and modifier adverbs. For example, in the sentence She sang very well, the expression very well is an adverbial phrase, as it modifies the verb to sing. More specifically, the adverbial phrase very well contains two adverbs, very and well: while well modifies the verb to convey information about the manner of singing, very is a degree modifier that conveys information about the degree to which the action of singing well was accomplished.
In descriptions of the Japanese language, an adjectival noun, adjectival, or na-adjective is a noun that can function as an adjective by taking the particle 〜な -na. Adjectival nouns constitute one of several Japanese word classes that can be considered equivalent to adjectives.
English prepositions are words – such as of, in, on, at, from, etc. – that function as the head of a prepositional phrase, and most characteristically license a noun phrase object. Semantically, they most typically denote relations in space and time. Morphologically, they are usually simple and do not inflect. They form a closed lexical category.
English adverbs are words such as so, just, how, well, also, very, even, only, really, and why that head adverb phrases, and whose most typical members function as modifiers in verb phrases and clauses, along with adjective and adverb phrases. The category is highly heterogeneous, but a large number of the very typical members are derived from adjectives + the suffix -ly and modify any word, phrase or clause other than a noun. Adverbs form an open lexical category in English. They do not typically license or function as complements in other phrases. Semantically, they are again highly various, denoting manner, degree, duration, frequency, domain, modality, and much more.
An attributive verb is a verb that modifies a noun in the manner of an attributive adjective, rather than express an independent idea as a predicate.
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.
An expletive attributive is an adjective or adverb that does not contribute to the meaning of a sentence, but is used to intensify its emotional force. Often such words or phrases are regarded as profanity or "bad language", though there are also inoffensive expletive attributives. The word is derived from the Latin verb explere, meaning "to fill", and it was originally introduced into English in the 17th century for various kinds of padding.
A predicative expression is part of a clause predicate, and is an expression that typically follows a copula or linking verb, e.g. be, seem, appear, or that appears as a second complement of a certain type of verb, e.g. call, make, name, etc. The most frequently acknowledged types of predicative expressions are predicative adjectives and predicative nominals. The main trait of all predicative expressions is that they serve to express a property that is assigned to a "subject", whereby this subject is usually the clause subject, but at times it can be the clause object. A primary distinction is drawn between predicative and attributive expressions. Further, predicative expressions are typically not clause arguments, and they are also typically not clause adjuncts. There is hence a three-way distinction between predicative expressions, arguments, and adjuncts.
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.
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.
