Grammatical categoryIn linguistics, a grammatical category or grammatical feature is a property of items within the grammar of a language. Within each category there are two or more possible values (sometimes called grammemes), which are normally mutually exclusive.
AdverbAn 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. Adverbs are traditionally regarded as one of the parts of speech.
Genitive caseIn grammar, the genitive case (abbreviated ) is the grammatical case that marks a word, usually a noun, as modifying another word, also usually a noun—thus indicating an attributive relationship of one noun to the other noun. A genitive can also serve purposes indicating other relationships. For example, some verbs may feature arguments in the genitive case; and the genitive case may also have adverbial uses (see adverbial genitive). Genitive construction includes the genitive case, but is a broader category.
PossessiveA possessive or ktetic form (abbreviated or ; from possessivus; κτητικός) is a word or grammatical construction indicating a relationship of possession in a broad sense. This can include strict ownership, or a number of other types of relation to a greater or lesser degree analogous to it. Most European languages feature possessive forms associated with personal pronouns, like the English my, mine, your, yours, his and so on. There are two main ways in which these can be used (and a variety of terminologies for each): Together with a noun, as in my car, your sisters, his boss.
Comparison (grammar)Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are rendered in an inflected or periphrastic way to indicate a comparative degree, property, quality, or quantity of a corresponding word, phrase, or clause. A superlative construction expresses the greatest quality, quantity, or degree relative to all other comparators. The associated is degree of comparison.
Bound and free morphemesIn linguistics, a bound morpheme is a morpheme (the elementary unit of morphosyntax) that can appear only as part of a larger expression, while a free morpheme (or unbound morpheme) is one that can stand alone. A bound morpheme is a type of bound form, and a free morpheme is a type of free form. A form is a free form if it can occur in isolation as a complete utterance, e.g. Johnny is running, or Johnny, or running (this can occur as the answer to a question such as What is he doing?).
Noun phraseA noun phrase, or nominal (phrase), is a phrase that has a noun or pronoun as its head or performs the same grammatical function as a noun. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type. Noun phrases often function as verb subjects and objects, as predicative expressions and as the complements of prepositions. Noun phrases can be embedded inside each other; for instance, the noun phrase some of his constituents contains the shorter noun phrase his constituents.
Grammatical tenseIn grammar, tense is a that expresses time reference. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns. The main tenses found in many languages include the past, present, and future. Some languages have only two distinct tenses, such as past and nonpast, or future and nonfuture. There are also tenseless languages, like most of the Chinese languages, though they can possess a future and nonfuture system typical of Sino-Tibetan languages.
Possessive determinerPossessive 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. Examples in English include possessive forms of the personal pronouns, namely: my, your, his, her, its, our and their, but excluding those forms such as mine, yours, ours, and theirs that are used as possessive pronouns but not as determiners.
DefinitenessIn linguistics, definiteness is a semantic feature of noun phrases, distinguishing between referents or senses that are identifiable in a given context (definite noun phrases) and those which are not (indefinite noun phrases). The prototypical definite noun phrase picks out a unique, familiar, specific referent such as the sun or Australia, as opposed to indefinite examples like an idea or some fish.
