'unclawed' is formed by the negative prefix 'un-' + the adjective/past participle 'clawed' (from 'claw'). 'un-' is from Old English/Germanic origin meaning 'not'.

'claw' originates from Old English 'clawu' (or similar forms in early Germanic languages) meaning 'claw, nail'. 'claw' developed into the past-participial/adjectival form 'clawed', and adding the prefix 'un-' produced 'unclawed' in modern English.

Originally, 'claw' referred to the physical 'claw' or 'nail'. Over time, adding 'un-' to the adjective/past participle 'clawed' gave the straightforward negative meaning 'not having claws', which is the current usage of 'unclawed'.
