City centre providing fish (4)
I believe the answer is:
chub
'fish' is the definition.
(chub is a kind of fish)
'city centre' is the wordplay.
'city' becomes 'c' (this might be a standard abbreviation I've not previously seen).
'centre' becomes 'hub' (hub is a kind of centre).
'c'+'hub'='CHUB'
'providing' is the link.
Can you help me to learn more?
(Other definitions for chub that I've seen before include "Fat freshwater fish" , "Thick-bodied European fish" , "Fat relative of the carp" , "Small river fish of the carp family" , "European freshwater fish" .)
