wifman meant "female human" (
man or
mann had a default meaning of "male human," but could also be used generically to refer to a person of unspecified gender, corresponding to Modern English "one" or "someone").
[1] The medial labial consonants coalesced to create the modern form "woman"; the initial element, which meant "female," underwent semantic narrowing to the sense of a married woman ("wife").
