"Form of Lady"
The name Leydi is commonly a female name from the "English" origin.
Leydi is a respelling of the English name Lady. The spelling follows Spanish conventions, in which ey represents the ay sound and a final i represents the final ee, so the written form matches the pronunciation rather than the English spelling. It carries no separate meaning of its own.
Lady means "One who kneads bread; the head of the house".
The pronunciation of Leydi is LAY-dee.
