Means “doe, female deer, gazelle”. It is taken from the Hebrew phrase אַיֶלֶת הַשַׁחַר (‘ayelet hashachar), literally “gazelle of dawn”, which is a name of the morning star.
From Turkish and Azerbaijani ayaz meaning “frost” or “dry and cold air”. This was the name of a slave and later companion of the 11th-century sultan Mahmud of Ghazni.
