'noncultivated' originates from English, formed from the prefix 'non-' (ultimately from Latin 'non', where 'non' meant 'not') and 'cultivated', which comes from Latin 'cultivatus' (from 'cultivare'), where 'cultivare' meant 'to till; to cultivate'.

'cultivate' changed from Latin 'cultivare' into Old French 'cultiver' and then into Middle English (e.g. 'cultiven'/'cultivate'); the modern English negated form 'noncultivated' arose by attaching the productive prefix 'non-' to 'cultivated' in later English usage.

Initially it meant 'not tilled or farmed' (a literal agricultural sense); over time the term was also used more broadly or metaphorically to mean 'not cultured or refined'.
