'unemotionally' originates from the prefix 'un-' meaning 'not' and the word 'emotional,' which comes from the Latin 'emovere,' where 'e-' meant 'out' and 'movere' meant 'to move.'

'emovere' transformed into the French word 'émouvoir,' and eventually became the modern English word 'emotional' through Middle English.

Initially, it meant 'to move out or stir,' but over time it evolved into its current meaning of 'relating to emotions.'
