Huge obscurity surrounding a keen unionist? (8)
I believe the answer is:
bigamist
'keen unionist?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'huge obscurity surrounding a' is the wordplay.
'huge' becomes 'big' (similar in meaning).
'obscurity' becomes 'mist'.
'surrounding' means one lot of letters goes inside another.
'big'+'mist'='bigmist'
'bigmist' placed around 'a' is 'BIGAMIST'.
Can you help me to learn more?
(Other definitions for bigamist that I've seen before include "One with two other halves?" , "One married to two people at once" , "lawbreaking union member" , "member of two unions" , "Person who marries illegally - already wed (8)" .)
