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

'strong feeling' is the definition.
(I've seen this before)

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

(Other definitions for emotion that I've seen before include "Agitation of mind" , "Feeling of joy, love, hate etc" , "Feeling such as joy, sorrow and fear" , "sense" , "Strong feeling of joy, fear etc" .)

I've seen this clue in The Sun.
