'uncontrollably' originates from the word 'uncontrollable,' which is derived from the prefix 'un-' meaning 'not,' and the root 'control,' which comes from the Latin 'contrarotulare,' meaning 'to check against a register.'

'uncontrollable' changed from the Old French word 'contreroller' and eventually became the modern English word 'control.'

Initially, it meant 'unable to be controlled,' and this meaning has largely remained the same in modern usage.
