Go live under crooked gorge (11)
I believe the answer is:
overindulge
'gorge' is the definition.
(synonyms)
'go live under crooked' is the wordplay.
'crooked' is an anagram indicator (a crooked or disrupted version of the letters).
'go'+'live'+'under'='goliveunder'
'goliveunder' is an anagram of 'OVERINDULGE'.
(Other definitions for overindulge that I've seen before include "Spoil through lavish treatment" , "Spoil to excess" , "pig" , "Take to excess" , "Drink excessively" .)
