Barking resident in bank grabbing boob (7)
I believe the answer is:
terrier
'barking resident' is the definition.
I can't tell whether this definition defines the answer.
'bank grabbing boob' is the wordplay.
'bank' becomes 'tier' (both can mean a row of similar things).
'grabbing' is an insertion indicator.
'boob' becomes 'err' (both can mean to make an error).
'tier' placed around 'err' is 'TERRIER'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for terrier that I've seen before include "Short-bodied canine" , "Small, originally burrowing, dog" , "Dog - reservist" , "Dog bred for hunting" , "Sealyham, for example" .)
