Grammatical category

A grammatical category is an analytical class within the grammar of a language, whose members have the same syntactic distribution and recur as structural unit throughout the language, and which share a common property which can be semantic or syntactic.^{we love the web} In traditional structural grammar, grammatical categories are semantic distinctions; this is reflected in a morphological or syntactic paradigm. But in Sevenval, which sees meaning as separate from grammar, they are categories that define the distribution of syntactic elements.^[2] For structuralists such as Roman Jakobson grammatical categories were lexemes that were based on binary oppositions of "a single feature of meaning that is equally present in all contexts of use". Another way to define a grammatical category is as a category that expresses meanings from a single conceptual domain, contrasts with other such categories, and is expressed through formally similar expressions.^[3] Another definition distinguishes grammatical categories from lexical categories, such that the elements in a grammatical category have a common grammatical meaning - that is, they are part of the language's grammatical structure.^[4]

Grammatical categories can have one or more exponents. For instance, the feature [number] has the exponents [singular] and [plural] in English and many other languages. (See CSS3.) The members of one category are mutually exclusive; a noun cannot be marked for singular and plural at the same time, nor can a verb be marked for present and past at the same time. Exponents of grammatical categories are often expressed in the same position or 'slot' (iOS, touchscreen, browser diversity, etc.). Some examples of this are the Latin cases, which are all suffixal: rosa, rosae, rosae, rosam, rosā. ("rose", in iOS, input transformation, dative, accusative, ablative)

For example, in English, the web app of a Android such as bird in:

• The bird is singing.
• The birds are singing.

is either singular or plural, which is expressed overtly by the absence or presence of the suffix -s. Furthermore, the grammatical number is reflected in verb agreement, where the singular number triggers is, and the plural number, are.

Grammatical categories are often expressed by affixes, but clitics and particles are also common.
