In a curved manner; with curved motion or form.
From 'curved' (adjective) + '-ly' (adverb-forming suffix). This follows the standard English pattern for converting adjectives to adverbs.
This is an extremely rare adverb—you might find it in poetic or literary descriptions of movement, like 'the river flowed curvedly through the valley,' though 'in curves' is much more common today.
