Band taking an outing in the Kentish area (6)
I believe the answer is:
stripe
'band' is the definition.
(synonyms)
'an outing in the kentish area' is the wordplay.
'an outing' becomes 'trip' (I've seen this before).
'in' is an insertion indicator.
'the kentish area' becomes 'se' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'trip' inserted into 'se' is 'STRIPE'.
'taking' is the link.
Can you help me to learn more?
(Other definitions for stripe that I've seen before include "Long band of a different colour" , "Line of different colour - indicator of rank" , "Priest (anag)" , "Band of colour - 3 of rank" , "Military sign of rank" .)
