hind has the recorded history: As an adjective, probably a back-formation from Old English behindan ('behind'). The noun 'female deer' is from Old English hind, from Proto-Germanic *hindō. The history explains the modern form through the named earlier word or formation, without requiring a separate speculative ancestry. The etymology remains cautious where the history is cautious: comparisons, echoic formation, or disputed derivation do not make the ancestry more definite than the forms actually named. In present English, the adjective sense is "situated at the back; also a female red deer", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as hinder and behind, and in derivatives such as hindmost. Its semantic neighborhood includes rear, back, hinder, and posterior, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Old English hindan and Proto-Germanic *hinder.
