'curvedly' originates from English, specifically formed from the adjective 'curved' + the adverbial suffix '-ly'. The adjective 'curved' ultimately derives from Latin 'curvus' (meaning 'bent').

'curvedly' changed from the Modern English adjective 'curved' (itself from Middle English forms related to Old French and ultimately Latin 'curvus') by adding the productive English suffix '-ly' to form an adverb in Modern English.

Initially, the Latin root 'curvus' meant 'bent' or 'crooked'; over time the sense persisted in English as 'curved' and was extended to the adverb 'curvedly' meaning 'in a curved manner'.
