Turkish has three commonly used words for “uncle”: Amca, Dayı, Enişte; and three for “aunt”: Hala, Teyze, Yenge. Here is how to use them.
Turkish words for father’s (“Baba”) and mother’s (“Anne”) siblings and their spouses.
Father’s brother is “Amca”, mother’s brother is “Dayı”. An uncle not related by blood is “Enişte”. Father’s sister is “Hala”, mother’s sister is “Teyze”. An aunt not related by blood is “Yenge”.
In all but formal circumstances, it is common to address considerably older strangers as “Amca” (uncle) or “Teyze” (aunt). However, I was once referred to as “Enişte” — probably due to the fact that I’m a foreigner and therefore I belong to the large family of all Turks by marriage, not by blood.
