'beatably' originates from English, formed from the adjective 'beatable' (verb 'beat' + suffix '-able') plus the adverbial suffix '-ly'.

'beatably' derives from the Late Middle English adjective 'beatable' (from verb 'beat' + Old French/Latin-derived suffix '-able'), with the adverb-forming English suffix '-ly' (from Old English '-lic') added in later Middle English to create the adverbial form.

Initially, components meant 'able to be beaten' (adjective 'beatable'); over time the addition of '-ly' produced the adverb meaning 'in a manner that can be beaten', used to describe how something can be defeated or outperformed.
