Such means limited in small bank (7)
I believe the answer is:
slender
'such means limited' is the definition.
I can't judge whether this definition defines the answer.
'small bank' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'bank' becomes 'lender'.
's'+'lender'='SLENDER'
'in' is the link.
Can you help me to learn more?
(Other definitions for slender that I've seen before include "Slim and supple" , "Svelte" , "Gracefully thin and elegant" , "short of a pound or two of flesh?" , "with a narrow outlook" .)
