Kezden

Kezden is a Turkish time expression formed from the noun kez (time, occasion) plus the ablative suffix den. It functions as a bound morpheme that marks the starting point of a period in time and is typically used in combination with other words to form phrases such as ilk kezden beri or son kezden beri, meaning “since the very first time” and “since the last time,” respectively. In standard Turkish, kezden usually appears in fixed phrases rather than as a free-standing lexical item.

Etymology and morphology: Kezden derives from kez with the addition of den, the ablative suffix. As a grammatical construction, it does not have a separate independent meaning beyond indicating a temporal starting point; its sense is relational, tying a time point to a span of time that follows.

Usage: Kezden is most common in formal narration, historical descriptions, and set phrases. It helps specify when a period began, especially when discussing continuities or changes from a referenced time. It is often paired with beri to express ongoing duration from that starting point.

Examples:

- İktisadi politikalar, ilk kezden beri revize ediliyor. (Since the very first time, these policies have been revised.)

- Kezden beri süregelen sorunlar çözüldü. (The problems that have persisted since that time were resolved.)
