'sturgeon' originates from Middle English, specifically the word 'sturgen,' which came from Old French 'esturgeon,' derived from the Vulgar Latin '*sturio,' from the Germanic root 'sturjo,' meaning 'sturgeon.'

'esturgeon' transformed into the Middle English word 'sturgen,' and eventually became the modern English word 'sturgeon.'

Initially, it meant 'a type of fish,' and this meaning has largely remained the same in modern usage.
