yürüdü

Yürüdü is the third-person singular past tense form of the Turkish verb yürümek, meaning "to walk." It is used to indicate that someone or something walked in the past and that the action is completed. The form shows past time through the suffix -di, with vowel harmony producing -dü in this case, so yürümek becomes yürüdü when conjugated for he/she/it.

Morphologically, yürüdü consists of the verb stem yür- (from yürümek) plus the simple past tense suffix di, adjusted to the stem’s vowel for harmony, yielding the combination -dü. Turkish verbs express person and number through suffixes; for example, I walked is yürüdüm, you walked is yürüdün, we walked is yürüdük, you all walked is yürüdünüz, and they walked is yürüdüler. The bare form yürüdü implies a third-person referent and is often used with an explicit subject or in a broader narrative context.

Usage notes include that yürüdü is common in both spoken and written Turkish and is employed in a variety of registers to report past events, especially in narrative and descriptive passages. It can be complemented by time expressions such as dün, o zaman, or bugün to situate the action in time. Related forms derive from the same verb stem: yürümek (to walk), to walk; present tense forms like yürüyor, and other past-tense forms such as yürüdüm or yürüdüler.

Etymology traces yürüdü to Turkish yürümek, with yür- as the root and -dü as the past tense marker, reflecting typical Turkish vowel harmony and agglutinative verb morphology.
