In a flexible manner; able to bend easily or adapt to different situations or changes.
From 'flexible' plus the adverb-forming suffix '-ly,' ultimately tracing to Latin 'flexibilis' meaning 'capable of bending.'
Adding '-ly' to an adjective is how English turns qualities into actions—it's why 'quickly' comes from 'quick' and 'flexibly' comes from 'flexible,' a pattern that's existed since Old English times.
