Godiva initially enters naked jog (5)
I believe the answer is:
nudge
'jog' is the definition.
(thesaurus)
'godiva initially enters naked' is the wordplay.
'initially' says to take the initial letters.
'enters' is an insertion indicator.
'naked' becomes 'nude' ('nude' can be a synonym of 'naked').
The first letter of 'godiva' is 'g'.
'g' put within 'nude' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Gentle prod" , "Push with the elbow" , "Push gently" , "Festive entertainment" , "Light touch or push" .)
