It's part of lover to need suggestion (8)
I believe the answer is:
overtone
'suggestion' is the definition.
(I've seen this before)
'it's part of lover to need' is the wordplay.
'it's part of' indicates a hidden word.
'OVERTONE' is hidden in the letters of 'lover to need'.
(Other definitions for overtone that I've seen before include "part of harmonic series" , "Nuance" , "Subtle implication or connotation" , "Hint" , "Suggestion" .)
