'tentatively-formed' originates from the word 'tentative,' which comes from the Latin 'tentativus,' meaning 'trying' or 'attempting.' The suffix '-ly' is used to form adverbs, and 'formed' is derived from the Old English 'geformed,' meaning 'to shape or create.'

'tentative' evolved from the Latin 'tentativus' through Old French 'tentatif,' and 'formed' from Old English 'geformed.' The combination of these words in modern English results in 'tentatively-formed.'

Initially, 'tentative' meant 'trying' or 'attempting,' and 'formed' meant 'to shape or create.' Together, they convey the idea of something shaped in a provisional manner.
