Elbow uncovered with force (5)
I believe the answer is:
nudge
'elbow' is the definition.
(synonyms)
'uncovered with force' is the wordplay.
'uncovered' becomes 'nude' (I've seen this in another clue).
'with' is an insertion indicator.
'force' becomes 'G' (short for gravity).
'nude' enclosing 'g' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "---. ---, wink, wink (Monty Python)" , "Push with the elbow" , "Gentle poke with elbow" , "Dig with elbow" , "Gentle encouragement" .)
