günleriyle
"Günleriyle" is a Turkish grammatical construction that translates literally to "with its days." It is a locative plural form used to indicate a period of time, often implying a habitual or recurring action within that timeframe. The suffix "-leriyle" is a possessive plural suffix that attaches to the word "gün" (day), which has already been placed in the locative case with the suffix "-de" (making it "günlerde" meaning "in the days"). Therefore, "günleriyle" signifies "with its days" or more idiomatically, "during its days" or "in its time."
This phrase is commonly employed in contexts describing events that happened or are happening over a span
