'bentgrass' originates from Old English, specifically the word 'beonet,' where 'beonet' referred to a type of grass or reed.

'beonet' transformed into the Middle English word 'bent,' and eventually became the modern English word 'bentgrass.'

Initially, it referred to any type of grass or reed, but over time it evolved into its current meaning of a specific type of grass used in lawns and golf courses.
