Jog naked around centre of Margate (5)
I believe the answer is:
nudge
'jog' is the definition.
(thesaurus)
'naked around centre of margate' is the wordplay.
'naked' becomes 'nude' ('nude' can be a synonym of 'naked').
'around' is an insertion indicator.
'centre of' means to look at the middle letters.
The central letter of 'margate' is 'g'.
'nude' placed around 'g' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Jog" , "Push with the elbow" , "A gentle reminder?" , "Remind, prompt gently" , "Push; prompt" .)
