Outgoing type of regular mermaid girl, eh? (6)
I believe the answer is:
emigre
'outgoing type' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'regular mermaid girl eh?' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'em' and 'em' is located in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for emigre that I've seen before include "One forced to leave one's country for political reasons" , "One in political exile" , "One leaving their nation" , "A political exile from regime" , "Political refugee, especially a royalist fleeing the French Revolution" .)
