Questions & Answers about Her akşam nehir kıyısında yürürüm.
Her is a distributive word meaning “each/every.” When you put it before a time noun like akşam (“evening”), her akşam means “every evening.”
In Turkish, a noun immediately following her cannot take additional case or plural endings, so her akşamda would be ungrammatical. If you want a general sense of “in the evenings,” you can use akşamları (“evenings” with a plural/ablative meaning “during evenings”), but you never add -da directly to her akşam.
Yes. Turkish word order is quite flexible for adverbials (time/place phrases).
– Her akşam nehir kıyısında yürürüm (Time–Place–Verb) is very natural.
– Nehir kıyısında her akşam yürürüm (Place–Time–Verb) is also perfectly fine.
– You could even say Yürürüm her akşam nehir kıyısında to emphasize the verb.
All these versions convey the same basic meaning; you simply shift emphasis by changing the order.
Nehir kıyısında is in the locative case, which answers the question “Where?”
– The locative suffix is -nda/-nde (after vowel harmony).
Here it tells us “at/on the riverbank.”
