Jog naked, skirting centre of Tangier (5)
I believe the answer is:
nudge
'jog' is the definition.
(I've seen this in another clue)
'naked skirting centre of tangier' is the wordplay.
'naked' becomes 'nude' (synonyms).
'skirting' means one lot of letters goes inside another.
'centre of' means to look at the middle letters.
The central letter of 'tangier' is 'g'.
'nude' placed around 'g' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Gentle poke with elbow" , "Gentle encouragement" , "Push (with a wink?)" , "Remind, prompt gently" , "suggestive move" .)
