sürdürdünüz

Sürdürdünüz is a Turkish verb form derived from the verb sürdürmek, which means to continue, maintain, or sustain. It is the simple past (definite past) conjugation used for second person plural, a form that is also used for formal address to a single person in Turkish. Therefore, sürdürdünüz translates roughly as you continued or you maintained, with the action completed in the past.

Formation and morphology: The infinitive sürdürmek provides the stem sürdür-. The past tense is marked with the suffix -dü, and the second person plural or formal you suffix -nüz is added to yield the ending -dünüz. The final form is thus sürdürdünüz. Turkish spelling reflects vowel harmony and consonant alternations within the stem and suffixes, but the standard written form is sürdürdünüz.

Usage and nuances: Sürdürdünüz is used when addressing a group or when using a polite form to address a single person in the past. It indicates that the subject(s) continued or maintained some action, state, or process. Examples include sentences like “Projeyi sürdürdünüz” (You continued the project) or “Planı sürdürdünüz” (You maintained the plan). For other persons, different endings are used (sürdürdüm, sürdürdün, sürdürdü, sürdürdük, sürdürdünüz, sürdüler).
