This is the 11069th most frequent Turkish word.
doğmasın
"Doğmasın" means "Let it not be born" or "May it not be born."
'Doğmasın' in this instance is used in an optative sense, expressing a wish that the event (the rising of the sun) does not happen.
Güneş doğmasın diye kalın perdeleri çektim.
I closed the heavy curtains so that the sun won't rise.
Here 'doğmasın' is employed metaphorically, meaning 'come into being' or 'arise,' indicating a wish or hope for non-occurrence.
O, hiçbir şeyden doğmasın, çünkü hatalar çoğu zaman zorluk getirir.
May nothing arise from it, because errors often bring challenges.
'Doğmasın' conveys the speaker's hope for avoiding a bad outcome, again metaphorically suggesting that no negative result 'emerges'.
