Credit frequently given to small farm (5)
I believe the answer is:
croft
'small farm' is the definition.
(Scottish term for a small farm)
'credit frequently given' is the wordplay.
'credit' becomes 'cr' (abbreviation).
'frequently' becomes 'oft' (oft can mean frequently, eg oft-quoted).
'given' says to put letters next to each other.
'cr'+'oft'='CROFT'
'to' acts as a link.
(Other definitions for croft that I've seen before include "Small farm in Scotland" , "Scottish smallholding" , "Farm up north" , "Virgin Mary's husband" , "Scottish farmstead" .)
