Something that can be added to Pennine town (6)
I believe the answer is:
bolton
'town' is the definition.
(I've seen this before)
'something that can be added to pennine' is the wordplay.
I cannot really understand how this works, but
'to' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bolton that I've seen before include "Additional" , "Piece of Greater Manchester" , "Greater Manchester town with a "Wanderers" football club" , "Non-world-beaters (anag)" , "Lancashire town" .)
