I believe the answer is:

affection

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

'feeling' is the definition.
(affection is a kind of feeling)

I don't understand how the rest of the clue works.

(Other definitions for affection that I've seen before include "Warm regard" , "Goodwill" , "Feeling of love or strong liking" , "Fondness, tenderness" , "Feeling of fondness" .)

I've seen this clue in The Sunday Times and The Times.
