A word to distinguish between father's and mother's sister [duplicate]
Maybe “paternal aunt” = "عمة" and “maternal aunt” = "خالة" would work. I’ve never heard of a one-word equivalent of them in English.
From Wikipedia (entry for "distaff"):
The term distaff is used to describe the female side of a family. The corresponding term for the male side of a family is the "spear" side.
So "distaff aunt/uncle"; or "spear aunt/uncle". (I've heard of distaff used in this sense...spear, not so much.)
