kák

Küçük is a Turkish adjective meaning "small" or "little." It is used to describe size, quantity, degree, or importance and is one of the most common modifiers in Turkish. In noun phrases, it usually precedes the noun: küçük ev (a small house), küçük çocuk (a small child). It can also function predicatively: Ev küçüktür (The house is small). Comparative and superlative forms are formed with daha and en: daha küçük (smaller) and en küçÜk (smallest).

The word is of Turkic origin and has cognates in related languages, such as Azerbaijani kiçik and Uzbek kichik, reflecting shared etymology and phonological development within the Turkic language family.

Küçük is also a common Turkish surname. As a surname it denotes historical or arbitrary meaning rather than a direct reference to size, and many individuals bear it as a family name. The term appears widely in Turkish literature, media, and everyday speech, including idiomatic expressions that extend beyond literal size to convey lesser degree or minor status.
