Aputsiaq is also used as a feminine name in Greenlandic. However, it's more common for males. So, I think that the "Gender" of this name should be changed from "Masculine" to "Masculine & Feminine". Some variants of this name are Aput, Aputsiaĸ, and Aputsiannguaq.
Pronounced ah-POOT-see-ahq. The Greenlandic q represents a sound not found in English or other European languages. It's sort of like a k, but very far back in the throat using almost a glottal stop.
