pounce: [15] Pounce was originally a noun, denoting the ‘claw of a bird of prey’. It is thought it may have come from puncheon ‘stamping or perforating tool’, which was also abbreviated to punch ‘stamping or perforating tool’ and is probably related to punch ‘hit’. The verb pounce emerged in the 17th century. It at first meant ‘seize with talons’, and was not generalized to ‘attack swoopingly’ until the 18th century.
