Agreement (linguistics)In linguistics, agreement or concord (abbreviated ) occurs when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some (such as gender or person) "agree" between varied words or parts of the sentence. For example, in Standard English, one may say I am or he is, but not "I is" or "he am". This is because English grammar requires that the verb and its subject agree in person.
DeclensionIn linguistics, declension (verb: to decline) is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection. Declensions may apply to nouns, pronouns, adjectives, adverbs, and articles to indicate number (e.g. singular, dual, plural), case (e.g. nominative case, accusative case, genitive case, dative case), gender (e.g. masculine, neuter, feminine), and a number of other grammatical categories. Meanwhile, the inflectional change of verbs is called conjugation.
CliticIn morphology and syntax, a clitic (ˈklɪtᵻk , backformed from Greek ἐγκλιτικός "leaning" or "enclitic") is a morpheme that has syntactic characteristics of a word, but depends phonologically on another word or phrase. In this sense, it is syntactically independent but phonologically dependent—always attached to a host. A clitic is pronounced like an affix, but plays a syntactic role at the phrase level. In other words, clitics have the form of affixes, but the distribution of function words.
Grammatical particleIn grammar, the term particle (abbreviated ) has a traditional meaning, as a part of speech that cannot be inflected, and a modern meaning, as a function word (functor) associated with another word or phrase, in order to impart meaning. Although a particle may have an intrinsic meaning, and may fit into other grammatical categories, the fundamental idea of the particle is to add context to the sentence, expressing a mood or indicating a specific action. In English, for example, the phrase "oh well" has no purpose in speech other than to convey a mood.
Reflexive pronounA reflexive pronoun is a pronoun that refers to another noun or pronoun (its antecedent) within the same sentence. In the English language specifically, a reflexive pronoun will end in -self or -selves, and refer to a previously named noun or pronoun (myself, yourself, ourselves, themselves, etc.). English intensive pronouns, used for emphasis, take the same form. In generative grammar, a reflexive pronoun is an anaphor that must be bound by its antecedent (see binding).
Pro-drop languageA pro-drop language (from "pronoun-dropping") is a language in which certain classes of pronouns may be omitted when they can be pragmatically or grammatically inferable. The precise conditions vary from language to language, and can be quite intricate. The phenomenon of "pronoun-dropping" is part of the larger topic of zero or null anaphora. The connection between pro-drop languages and null anaphora relates to the fact that a dropped pronoun has referential properties, and so is crucially not a null dummy pronoun.
DeterminerA determiner, also called determinative (abbreviated ), is a word, phrase, or affix that occurs together with a noun or noun phrase and generally serves to express the reference of that noun or noun phrase in the context. That is, a determiner may indicate whether the noun is referring to a definite or indefinite element of a class, to a closer or more distant element, to an element belonging to a specified person or thing, to a particular number or quantity, etc.
Singular theySingular they, along with its inflected or derivative forms, them, their, theirs and themselves (also themself, and theirself), is a gender-neutral third-person pronoun. It typically occurs with an indeterminate antecedent, in sentences such as: "Somebody left their umbrella in the office. Could you please let them know where they can get it?" "My personal rule is to never trust anyone who says that they had a good time in high school." "The patient should be told at the outset how much they will be required to pay.
Possession (linguistics)In linguistics, possession is an asymmetric relationship between two constituents, the referent of one of which (the possessor) in some sense possesses (owns, has as a part, rules over, etc.) the referent of the other (the possessed). Possession may be marked in many ways, such as simple juxtaposition of nouns, possessive case, possessed case, construct state (as in Arabic, and Nêlêmwa), or adpositions (possessive suffixes, possessive adjectives). For example, English uses a possessive clitic, 's; a preposition, of; and adjectives, my, your, his, her, etc.
Possessive affixIn linguistics, a possessive affix (from affixum possessivum) is an affix (usually suffix or prefix) attached to a noun to indicate its possessor, much in the manner of possessive adjectives. Possessive affixes are found in many languages of the world. The World Atlas of Language Structures lists 642 languages with possessive suffixes, possessive prefixes, or both out of a total sample of 902 languages. Possessive suffixes are found in some Austronesian, Uralic, Altaic, Semitic, and Indo-European languages.
