Type of ant and fish go inside (9)
I believe the answer is:
carpenter
'type of ant' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'fish go inside' is the wordplay.
'fish' becomes 'carp' (carp is a kind of fish).
'go inside' becomes 'enter' (I've seen this in another clue).
'carp'+'enter'='CARPENTER'
'and' is the link.
Can you help me to learn more?
(Other definitions for carpenter that I've seen before include "Wood worker" , "job" , "Woodworker (Quince)" , "He makes wooden objects and structures" , "Joseph's occupation" .)
