Grape is actually what we call "faux amis" (false friend because they are homophonic but with different meaning) in french with the french word 'grappe'. The french word for grape is actually 'raisin'. But 'une grappe de raisin' which is commonly used means 'a bunch of grapes'
For those who are curious, the loser in the Battle of Hastings was Harold II of England (or Harold Godwinson as his father was Godwin, Earl of Wessex).
Interestingly enough, we do remember King Cnut, whose sister married Harold II's uncle.
