SyntaxIn linguistics, syntax (ˈsɪntæks ) is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). There are numerous approaches to syntax that differ in their central assumptions and goals.
Grammatical numberIn linguistics, grammatical number is a feature of nouns, pronouns, adjectives and verb agreement that expresses count distinctions (such as "one", "two" or "three or more"). English and other languages present number categories of singular or plural, both of which are cited by using the hash sign (#) or by the numero signs "No." and "Nos." respectively. Some languages also have a dual, trial and paucal number or other arrangements.
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).
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).
Preposition and postpositionPrepositions and postpositions, together called adpositions (or broadly, in traditional grammar, simply prepositions), are a class of words used to express spatial or temporal relations (in, under, towards, before) or mark various semantic roles (of, for). A preposition or postposition typically combines with a noun phrase, this being called its complement, or sometimes object. A preposition comes before its complement; a postposition comes after its complement.
DemonstrativeDemonstratives (abbreviated ) are words, such as this and that, used to indicate which entities are being referred to and to distinguish those entities from others. They are typically deictic, their meaning depending on a particular frame of reference, and cannot be understood without context. Demonstratives are often used in spatial deixis (where the speaker or sometimes the listener is to provide context), but also in intra-discourse reference (including abstract concepts) or anaphora, where the meaning is dependent on something other than the relative physical location of the speaker.
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.
Grammatical personIn linguistics, grammatical person is the grammatical distinction between deictic references to participant(s) in an event; typically, the distinction is between the speaker (first person), the addressee (second person), and others (third person). A language's set of pronouns is typically defined by grammatical person. First person includes the speaker (English: I, we), second person is the person or people spoken to (English: thou or you ), and third person includes all that are not listed above (English: he, she, it, they).
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.
AdjectiveAn adjective (abbreviated adj.) is a word that describes a noun or noun phrase. Its semantic role is to change information given by the noun. Traditionally, adjectives were considered one of the main parts of speech of the English language, although historically they were classed together with nouns. Nowadays, certain words that usually had been classified as adjectives, including the, this, my, etc., typically are classed separately, as determiners. Here are some examples: That's a funny idea.
