Learn Hardcore Turkish: Kütüphane sessiz görünse de öğle saatinde oldukça gürültülü oluyor. - Although the library looks quiet, it becomes quite noisy at noon.

Görünse de is a concessive expression meaning “even though it appears” or “though it looks.” It’s formed by taking the verb görün- (to appear, to seem), adding the aorist subjunctive/concessive suffix -se, and then attaching -de, which in this construction means “even if.” So görün-se-de literally is “even if it seems.”

Why do we say sessiz görünse de instead of sessiz görünüyor ama?

Sessiz görünse de uses a single concessive subordinate clause with -se de (“even though…”). By contrast, sessiz görünüyor ama would be two independent clauses joined by ama (but). The -se de structure is more concise and idiomatic for “though it seems quiet…”

What is öğle saatinde, and why is there a -de suffix on saat?

Öğle saatinde means “at lunchtime” or “during the noon hours.” The noun saat (hour) takes the locative case suffix -de, indicating “in” or “at” a time. So saat+ -in + -de becomes saatinde, literally “in the hour of noon.”
