I believe the answer is:

yummy

I'm a little stuck... Click here to teach me more about this clue!

'attractive' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for yummy that I've seen before include "Mmmmm!" , "Very tasty" , "That's truly scrumptious!" , "Luscious" , "Mmmmmm!" .)

I've seen this clue in The Independent.
