'controversially-formed' originates from the word 'controversial,' which comes from the Latin 'controversia,' meaning 'dispute.' The suffix '-ly' is used to form adverbs, and 'formed' is derived from the Old English 'formian,' meaning 'to shape or create.'

'Controversial' evolved from the Latin 'controversia' through Old French 'controversie' and Middle English 'controversie,' eventually becoming 'controversial' in modern English. 'Formed' has remained relatively unchanged from its Old English roots.

Initially, 'controversial' meant 'pertaining to a dispute,' and 'formed' meant 'shaped or created.' The combined term 'controversially-formed' retains these meanings, emphasizing the contentious nature of the formation process.
