Chips, some say, go in after fish (9)
I believe the answer is:
carpenter
'chips some' is the definition.
'carpenter' can be an answer for 'chips' (chips can informally refer to a carpenter). I'm unsure of the 'some' bit.
'go in after fish' is the wordplay.
'go in' becomes 'enter' (as in entering a building).
'after' means one lot of letters go next to another.
'fish' becomes 'carp' (carp is a kind of fish).
'enter' after 'carp' is 'CARPENTER'.
'say' acts as a link.
Can you help me to learn more?
(Other definitions for carpenter that I've seen before include "artisan" , "Walrus' companion" , "Craftsman" , "singer called Karen" , "chips?" .)
