Origin: OE. Mouten, L. Mutare. See Mew to molt, and cf. Mute The prevalent spelling is, perhaps, moult; but as the u has not been inserted in the otherwords of this class, as, bolt, colt, dolt, etc, it is desirable to complete the analogy by the spelling molt.
To cast, as the hair, skin, feathers, or the like; to shed.
