'conventionally-changed' originates from the word 'convention,' which comes from Latin 'conventio,' meaning 'a coming together.' The suffix '-ally' indicates an adverbial form, and 'changed' is derived from Old French 'changier,' meaning 'to alter or exchange.'

'Convention' evolved from Latin 'conventio' to Old French 'convention,' and 'change' from Old French 'changier' to Middle English 'chaungen.'

Initially, 'convention' meant 'a formal meeting or assembly,' but over time it evolved to mean 'an accepted practice or standard.'
