Personal pronounPersonal pronouns are pronouns that are associated primarily with a particular grammatical person – first person (as I), second person (as you), or third person (as he, she, it, they). Personal pronouns may also take different forms depending on number (usually singular or plural), grammatical or natural gender, case, and formality. The term "personal" is used here purely to signify the grammatical sense; personal pronouns are not limited to people and can also refer to animals and objects (as the English personal pronoun it usually does).
Valency (linguistics)In linguistics, valency or valence is the number and type of arguments controlled by a predicate, content verbs being typical predicates. Valency is related, though not identical, to subcategorization and transitivity, which count only object arguments – valency counts all arguments, including the subject. The linguistic meaning of valency derives from the definition of valency in chemistry. Like valency found in chemistry, there is the binding of specific elements.
Topic-prominent languageA topic-prominent language is a language that organizes its syntax to emphasize the topic–comment structure of the sentence. The term is best known in American linguistics from Charles N. Li and Sandra Thompson, who distinguished topic-prominent languages, such as Korean and Japanese, from subject-prominent languages, such as English. In Li and Thompson's (1976) view, topic-prominent languages have morphology or syntax that highlights the distinction between the topic and the comment (what is said about the topic).
One (pronoun)One is an English language, gender-neutral, indefinite pronoun that means, roughly, "a person". For purposes of verb agreement it is a third-person singular pronoun, though it sometimes appears with first- or second-person reference. It is sometimes called an impersonal pronoun. It is more or less equivalent to the Scots "a body", the French pronoun on, the German/Scandinavian man, and the Spanish uno. It can take the possessive form one's and the reflexive form oneself, or it can adopt those forms from the generic he with his and himself.
Null-subject languageIn linguistic typology, a null-subject language is a language whose grammar permits an independent clause to lack an explicit subject; such a clause is then said to have a null subject. In the principles and parameters framework, the null subject is controlled by the pro-drop parameter, which is either on or off for a particular language. Typically, null-subject languages express person, number, and/or gender agreement with the referent on the verb, rendering a subject noun phrase redundant.
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.
Copula (linguistics)In linguistics, a copula (plural: copulas or copulae; abbreviated ) is a word or phrase that links the subject of a sentence to a subject complement, such as the word is in the sentence "The sky is blue" or the phrase was not being in the sentence "It was not being co-operative." The word copula derives from the Latin noun for a "link" or "tie" that connects two different things. A copula is often a verb or a verb-like word, though this is not universally the case. A verb that is a copula is sometimes called a copulative or copular verb.
