Live with craving to fascinate (7)
I believe the answer is:
bewitch
'to fascinate' is the definition.
(synonyms)
'live with craving' is the wordplay.
'live' becomes 'be' (synonyms).
'with' becomes 'w' (abbreviation).
'craving' becomes 'itch' (I've seen this in another clue).
'be'+'w'+'itch'='BEWITCH'
(Other definitions for bewitch that I've seen before include "Get intoxicated" , "Put under a spell, or delight" , "Captivate" , "Spellbind" , "add glamour" .)
