numberagreement

Number agreement refers to the grammatical requirement that a determiner, adjective, or verb must match the number of the noun it modifies or refers to. In English, this most commonly involves a distinction between singular and plural forms. For instance, a singular noun requires a singular determiner, as in "a book" or "this table." Conversely, a plural noun needs a plural determiner, such as "some books" or "these tables." Verbs also exhibit number agreement, particularly in the present tense. A singular subject typically takes a singular verb form, like "he walks" or "she eats." A plural subject, however, takes a plural verb form, exemplified by "they walk" or "we eat." This agreement ensures clarity and grammatical correctness within a sentence. Errors in number agreement can lead to awkward phrasing or miscommunication. While English has relatively straightforward number agreement rules, other languages may have more complex systems, involving distinctions for dual (two) or trial (three) numbers, or agreement with gender as well as number.
