Zin
Yes. Zin is best known from the classical Kurdish epic Mem û Zîn by Ahmad Khani (17th century) and is a longstanding Kurdish literary name.
In Kurdish literary use Zin is rendered as 'beauty', 'adornment', or 'beloved'. The Arabic cognate 'زين' also conveys 'beauty' or 'ornament'.
No. Zin is not a Qur'anic name; its authority comes from Kurdish literary and cultural traditions rather than scripture.
Mem û Zîn has been read by scholars and readers as containing mystical and allegorical layers; consequently, Zin can carry Sufi-flavored symbolism of yearning and spiritual beauty in cultural usage.
Commonly pronounced Zîn or Zeen (phonetic /ziːn/) in Kurdish; variant spellings reflect dialectal orthographies (Zîn, Zinê).
