Would Cockney one get double Dutch? (8)
I believe the answer is:
bigamist
'double dutch?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bigamist that I've seen before include "Law-breaker with more than one spouse" , "Person who marries while still married to another" , "One marries while already legally married to another" , "One who marries more than once illegally" , "One who unlawfully marries a second wife" .)
