Resembling, containing, or full of grapes; having qualities similar to grapes in taste or appearance.
From grape + -y suffix (forming adjectives meaning 'having the quality of'); 'grape' itself comes from Old French 'grape' (a bunch of grapes).
This humble adjective reveals why English is so flexible—we can add '-y' to almost any noun to describe something with that quality, which is why children can invent words like 'spaghetti-y' or 'cloud-y' and everyone understands.
