>### 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’.**
