Uncovered gout, initially, in elbow (5)
I believe the answer is:
nudge
'elbow' is the definition.
(synonyms)
'uncovered gout initially in' is the wordplay.
'uncovered' becomes 'nude' (I've seen this in another clue).
'initially' suggests taking the first letters.
'in' is an insertion indicator.
The initial letter of 'gout' is 'g'.
'nude' placed around 'g' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Gentle push" , "Gently encourage" , "A gentle reminder?" , "Jog" , "Push with the elbow" .)
