sufficient: [14] Sufficient originated as the present participle of Latin sufficere ‘be enough’ (source also of English suffice [14]). This was a compound verb formed from the prefix sub- ‘under’ and facere ‘do, make’ (source of English fact, factory, etc). It originally meant literally ‘put under’, and the notion of ‘enough’ evolved via ‘cause to take the place of’.
