'uncreatively' originates from English, specifically formed from the adjective 'uncreative', where the prefix 'un-' meant 'not' (from Old English 'un-') and the root 'creative' ultimately comes from Latin 'creare' meaning 'to create'; the suffix '-ly' (from Old English '-lic') gives it an adverbial form.

'creative' came into English from Late Latin 'creativus' via Old French 'creatif' and Middle English; the Old English prefix 'un-' was added to form 'uncreative' in Modern English, and the adverbial suffix '-ly' was then attached to make 'uncreatively'.

Initially, the elements meant 'not' and 'to create', but over time the compounded form evolved to mean 'in a manner lacking originality or imagination', the current usage of 'uncreatively'.
