Topic and commentIn linguistics, the topic, or theme, of a sentence is what is being talked about, and the comment (rheme or focus) is what is being said about the topic. This division into old vs. new content is called information structure. It is generally agreed that clauses are divided into topic vs. comment, but in certain cases the boundary between them depends on which specific grammatical theory is being used to analyze the sentence. The topic of a sentence is distinct from the grammatical subject.
GerundIn linguistics, a gerund (ˈdʒɛɹənd,_-ʌnd abbreviated ger) is any of various nonfinite verb forms in various languages; most often, but not exclusively, one that functions as a noun. In English, it has the properties of both verb and noun, such as being modifiable by an adverb and being able to take a direct object. The term "-ing form" is often used in English to refer to the gerund specifically.
Head-marking languageA language is head-marking if the grammatical marks showing agreement between different words of a phrase tend to be placed on the heads (or nuclei) of phrases, rather than on the modifiers or dependents. Many languages employ both head-marking and dependent-marking, and some languages double up and are thus double-marking. The concept of head/dependent-marking was proposed by Johanna Nichols in 1986 and has come to be widely used as a basic category in linguistic typology.
Object pronounIn linguistics, an object pronoun is a personal pronoun that is used typically as a grammatical object: the direct or indirect object of a verb, or the object of a preposition. Object pronouns contrast with subject pronouns. Object pronouns in English take the objective case, sometimes called the oblique case or object case. For example, the English object pronoun me is found in "They see me" (direct object), "He's giving me my book" (indirect object), and "Sit with me" (object of a preposition); this contrasts with the subject pronoun in "I see them," "I am getting my book," and "I am sitting here.
Raising (linguistics)In linguistics, raising constructions involve the movement of an argument from an embedded or subordinate clause to a matrix or main clause. In other words, a raising predicate/verb appears with a syntactic argument that is not its semantic argument but rather the semantic argument of an embedded predicate. For example, in they seem to be trying, the predicand of trying is the subject of seem. English has raising constructions, unlike some other languages.
Dummy pronounA dummy pronoun is a deictic pronoun that fulfills a syntactical requirement without providing a contextually explicit meaning of its referent. As such, it is an example of exophora. Dummy pronouns are used in many Germanic languages, including German and English. Pronoun-dropping languages such as Spanish, Portuguese, Chinese, and Turkish do not require dummy pronouns.
Traditional grammarTraditional grammar (also known as classical grammar) is a framework for the description of the structure of a language. The roots of traditional grammar are in the work of classical Greek and Latin philologists. The formal study of grammar based on these models became popular during the Renaissance. Traditional grammars may be contrasted with more modern theories of grammar in theoretical linguistics, which grew out of traditional descriptions.
PredicandIn semantics, a predicand is an argument in an utterance, specifically that of which something is predicated. By extension, in syntax, it is the constituent in a clause typically functioning as the subject. In the most typical cases, the predicand corresponds to the subject of a clause, and the predicate corresponds to a verb phrase (VP) that is the head of the clause. But there are also form-meaning mismatches, where the predicand is not a subject or where the predicate is not the head of the clause.
Subject–auxiliary inversionSubject–auxiliary inversion (SAI; also called subject–operator inversion) is a frequently occurring type of inversion in English, whereby a finite auxiliary verb – taken here to include finite forms of the copula be – appears to "invert" (change places) with the subject. The word order is therefore Aux-S (auxiliary–subject), which is the opposite of the canonical SV (subject–verb) order of declarative clauses in English.
Yes–no questionIn linguistics, a yes–no question, also known as a binary question, a polar question, or a general question, is a question whose expected answer is one of two choices, one that provides an affirmative answer to the question versus one that provides a negative answer to the question. Typically, in English, the choices are either "yes" or "no". Yes–no questions present an exclusive disjunction, namely a pair of alternatives of which only one is a felicitous answer.
