They simply adore left-overs! (6)

I believe the answer is:

lovers

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

'they simply adore' is the definition.
The definition suggests an adverb but the answer is not.

'left-overs' is the wordplay.
'left' becomes 'l' (common abbreviation).
'l'+'overs'='LOVERS'

Can you help me to learn more?

(Other definitions for lovers that I've seen before include "Romeo and Juliet, perhaps" , "Romantic pair" , "Fans" .)

I've seen this clue in the Evening Standard.
