Small amount of paper for a country gentleman (6)
I believe the answer is:
squire
'a country gentleman' is the definition.
(I've seen this before)
'small amount of paper' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'amount of paper' becomes 'quire' (I've seen this before).
's'+'quire'='SQUIRE'
'for' acts as a link.
(Other definitions for squire that I've seen before include "[PILGRIM in the CANTERBURY TALES]" , "Local landowner; knight's attendant" , "English country landowner" , "Chief landowner of an area" , "Old landowner" .)
