A morpheme is the smallest meaningful constituent of a linguistic expression. The field of linguistic study dedicated to morphemes is called morphology.
Native Esperanto speakers are people who have acquired Esperanto as one of their native languages. As of 1996, there were 350 or so attested cases of families with native Esperanto speakers. Estimates from associations indicate that there were around 1,000 Esperanto-speaking families, involving perhaps 2,000 children in 2004. According to a 2019 synthesis of all the estimates made, they would be between several hundred and 2000, and would compose between <1% and 4.5% of the Esperanto community. In all known cases, speakers are natively bilingual, or multilingual, raised in both Esperanto and either the local national language or the native language of their parents. In all but a handful of cases, it was the father who used Esperanto with the child. In the majority of such families, the parents had the same native language, though in many the parents had different native languages, and only Esperanto in common.
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 idiom is a phrase or expression that usually presents a figurative, non-literal meaning attached to the phrase. Some phrases which become figurative idioms, however, do retain the phrase's literal meaning. Categorized as formulaic language, an idiom's figurative meaning is different from the literal meaning. Idioms occur frequently in all languages; in English alone there are an estimated twenty-five million idiomatic expressions.
Morphological derivation, in linguistics, is the process of forming a new word from an existing word, often by adding a prefix or suffix, such as un- or -ness. For example, unhappy and happiness derive from the root word happy.
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 corpus linguistics, a collocation is a series of words or terms that co-occur more often than would be expected by chance. In phraseology, a collocation is a type of compositional phraseme, meaning that it can be understood from the words that make it up. This contrasts with an idiom, where the meaning of the whole cannot be inferred from its parts, and may be completely unrelated.
In linguistics, a compound is a lexeme that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. Consequently, a compound is a unit composed of more than one stem, forming words or signs. If the joining of the words or signs is orthographically represented with a hyphen, the result is a hyphenated compound. If they are joined without an intervening space, it is a closed compound. If they are joined with a space, then the result – at least in English – may be an open compound.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
In linguistics, the term lexis designates the complete set of all possible words in a language, or a particular subset of words that are grouped by some specific linguistic criteria. For example, the general term English lexis refers to all words of the English language, while more specific term English religious lexis refers to a particular subset within English lexis, encompassing only words that are semantically related to the religious sphere of life.
In lexicography, a lexical item is a single word, a part of a word, or a chain of words (catena) that forms the basic elements of a language's lexicon (≈ vocabulary). Examples are cat, traffic light, take care of, by the way, and it's raining cats and dogs. Lexical items can be generally understood to convey a single meaning, much as a lexeme, but are not limited to single words. Lexical items are like semes in that they are "natural units" translating between languages, or in learning a new language. In this last sense, it is sometimes said that language consists of grammaticalized lexis, and not lexicalized grammar. The entire store of lexical items in a language is called its lexis.
A phraseme, also called a set phrase, fixed expression, idiomatic phrase, multiword expression, or idiom, is a multi-word or multi-morphemic utterance whose components include at least one that is selectionally constrained or restricted by linguistic convention such that it is not freely chosen. In the most extreme cases, there are expressions such as X kicks the bucket ≈ ‘person X dies of natural causes, the speaker being flippant about X’s demise’ where the unit is selected as a whole to express a meaning that bears little or no relation to the meanings of its parts. All of the words in this expression are chosen restrictedly, as part of a chunk. At the other extreme, there are collocations such as stark naked, hearty laugh, or infinite patience where one of the words is chosen freely based on the meaning the speaker wishes to express while the choice of the other (intensifying) word is constrained by the conventions of the English language. Both kinds of expression are phrasemes, and can be contrasted with ’’free phrases’’, expressions where all of the members are chosen freely, based exclusively on their meaning and the message that the speaker wishes to communicate.
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.
A fossil word is a word that is broadly obsolete but remains in current use due to its presence within an idiom or phrase. An example for a word sense is 'ado' in 'much ado'. An example for a phrase is 'in point' (relevant), which is retained in the larger phrases 'case in point' and 'in point of fact', but is rarely used outside of a legal context.
In linguistics an accidental gap, also known as a gap, paradigm gap, accidental lexical gap, lexical gap, lacuna, or hole in the pattern, is a potential word, word sense, morpheme, or other form that does not exist in some language despite being theoretically permissible by the grammatical rules of that language. For example, a word pronounced is theoretically possible in English, as it would obey English word-formation rules, but does not currently exist. Its absence is therefore an accidental gap, in the ontologic sense of the word accidental.
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.
In linguistics, a catena is a unit of syntax and morphology, closely associated with dependency grammars. It is a more flexible and inclusive unit than the constituent and its proponents therefore consider it to be better suited than the constituent to serve as the fundamental unit of syntactic and morphosyntactic analysis.
In the traditional grammar of Modern English, a phrasal verb typically constitutes a single semantic unit consisting of a verb followed by a particle, sometimes collocated with a preposition.
Idiom, also called idiomaticness or idiomaticity, is the syntactical, grammatical, or structural form peculiar to a language. Idiom is the realized structure of a language, as opposed to possible but unrealized structures that could have developed to serve the same semantic functions but did not.
