rma bya:

It can be speculated that etymologically peacock/peahen is a bird (bya) with feathers that look like patterns or patches of wound (rma). But as pointed out in Beyer 1992: 145, rma bya represents a type of “mixed form” that “combines a transfer with a native gloss on the meaning of the transferred element.” That is, rma is a native (meaningful) gloss of the Sanskrit root mā from which mayūra (“peacock”) is said to be probably derived. See MW (s.v. mayūra).
