In Belarusian grammar, the theory of articles deals with the usage and function of articles in the language. Unlike some other languages, Belarusian does not have definite or indefinite articles. Instead, it relies heavily on context and word order to determine the specificity or generality of a noun.

In Belarusian, a noun can stand alone without an article or be modified by an adjective, which provides additional information about the noun. Adjectives can also indicate definiteness or indefiniteness. For example, the adjective “сёлы” (blue) can be used before a noun to indicate definiteness, as in “сёлы стол” (the blue table), or it can be omitted for a more general sense, as in “стол” (table).

Additionally, word order plays a significant role in indicating definiteness or indefiniteness. Typically, definite nouns are placed at the beginning of a sentence or clause, while indefinite nouns are placed after the verb. For instance, “Дзевачка пісала” (The girl was writing) suggests a specific girl, while “Пісала дзевачка” (A girl was writing) implies any girl in general.

Overall, the absence of articles in Belarusian requires speakers to rely on context, adjectives, and word order to convey definiteness or indefiniteness.
