Connected when covering northern town (8)
I believe the answer is:
bridgend
'town' is the definition.
I know nothing about this answer so I can't judge whether this works.
'connected when covering northern' is the wordplay.
'connected' becomes 'bridged' (bridging is a kind of connecting).
'when covering' indicates putting letters inside.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'bridged' enclosing 'n' is 'BRIDGEND'.
Can you help me to learn more?
(Other definitions for bridgend that I've seen before include "Welsh location" , "Welsh town" .)
