Goes into chippies wanting fish (6)
I believe the answer is:
enters
'goes into' is the definition.
('enter' can be a synonym of 'go into')
'chippies wanting fish' is the wordplay.
'chippies' becomes 'carpenters' (chippy can informally mean a carpenter).
'wanting' indicates named letters should be taken away (wanting can mean lacking).
'fish' becomes 'carp' (carp is a kind of fish).
'carpenters' with 'carp' taken away is 'ENTERS'.
(Other definitions for enters that I've seen before include "Inserts" , "Registers for a competition, say" , "Goes in or records in book" , "Records, in a diary say" , "Comes in" .)
