Düzgün

Düzgün is a Turkish and Azerbaijani adjective meaning proper, correct, regular, or orderly. It can describe a person’s behavior as proper or well-mannered, a process or condition that conforms to standards, or a thing that is even, smooth, or level. In everyday use, it covers a range from moral or procedural propriety to physical regularity, such as a düzgün ölçü (proper measurement), düzgün davranış (proper conduct), or düzgün yüzey (even/smooth surface). It is also used to convey regularity or routine, for example a düzgün bir programa (a regular schedule).

Grammatical notes: Düzgün forms the noun düzgünlük, which means regularity, propriety, or correctness. The adverbial forms include düzgünce and, more commonly, düzgün şekilde, both conveying the sense of “properly” or “correctly.” Comparative and superlative constructions follow the standard Turkish pattern: daha düzgün, en düzgün.

Etymology and cognates: The word originates in Turkic languages, with parallel forms in Azerbaijani and other Turkic varieties. The exact historical development is not always clear, but the core sense of straight, smooth, or proper is preserved across related languages.
