Uncovered with force of elbow (5)
I believe the answer is:
nudge
'elbow' is the definition.
(I know that elbow is a more specific form of nudge)
'uncovered with force' is the wordplay.
'uncovered' becomes 'nude' (I've seen this in another clue).
'with' means one lot of letters goes inside another.
'force' becomes 'G' (short for gravity).
'nude' enclosing 'g' is 'NUDGE'.
'of' is the link.
(Other definitions for nudge that I've seen before include "Push with the elbow" , "Remind (with the elbow?)" , "Light touch or push" , "Prod gently with elbow" , "Festive entertainment" .)
