'alligate' originates from Latin, specifically the word 'alligatus,' where 'ad-' meant 'to' and 'ligare' meant 'to bind.'

'alligatus' transformed into the Medieval Latin word 'alligatus,' and eventually became the modern English word 'alligate.'

Initially, it meant 'to bind or tie something together,' and this meaning has largely remained the same in modern usage.
