Copper — married man from Kendal, say (8)
I believe the answer is:
cumbrian
'kendal say' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'copper married man' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'man' becomes 'brian' (man's name).
'cu'+'m'+'brian'='CUMBRIAN'
'from' acts as a link.
Can you help me to learn more?
(Another definition for cumbrian that I've seen is " from north of England".)
