Deliveli means literally "crazy guardian" (Turkish: deli + veli). Two different stories are given concerning the origin of the name:
Long ago, a man named Deli Veli (Veli the Crazy) was a respected elder of the village, and the village was named after him.
In the past, a wrestler named Veli lived in the area. Because he could defeat everyone, he earned the nickname "Deli" and the village was named after him.
History
A Byzantine-era stone block carved with a cross has been found in Deliveli; it was reused as part of a well.
