'devote' originates from Latin, specifically the word 'devotus,' where 'de-' meant 'away' and 'votum' meant 'a vow or promise.'

'devotus' transformed into the French word 'devot,' and eventually became the modern English word 'devote' through Middle English.

Initially, it meant 'to vow or dedicate oneself,' and this meaning has largely remained the same in modern usage.
