Small farm regularly pursuing credit (5)
I believe the answer is:
croft
'small farm' is the definition.
(Scottish term for a small farm)
'regularly pursuing credit' is the wordplay.
'regularly' becomes 'oft' (often).
'pursuing' says to put letters next to each other.
'credit' becomes 'cr'.
'oft' put after 'cr' is 'CROFT'.
(Other definitions for croft that I've seen before include "Scottish smallholding" , "Small Scottish rented farm" , "Plot" , "Small (Scots) farm" , "Virgin Mary's husband" .)
