Takes off for journeys to the south (6)
I believe the answer is:
strips
'takes off' is the definition.
(strip can mean to remove or take off)
'journeys to the south' is the wordplay.
'journeys' becomes 'trips' (trip is a kind of journey).
'to' says to put letters next to each other (I've seen this in other clues).
'the south' becomes 's' (abbreviation).
'trips' after 's' is 'STRIPS'.
'for' is the link.
(Other definitions for strips that I've seen before include "Gets undressed" , "Long narrow pieces" , "Peels off" , "outfits" , "Removes clothes" .)
