breed: breed: [OE] The Old English verb brēdan came from West Germanic *brōdjan, a derivative of *brōd-, which produced brood. This in turn was based on *brō-, whose ultimate source was the Indo-European base *bhrē- ‘burn, heat’ (its other English descendants include braise, breath, and probably brawn). The underlying notion of breed is thus not ‘reproduction’ so much as ‘incubation, the warmth which promotes hatching’.
=> braise, brawn, breath, brood
