Territory, so to speak (4)
I believe the answer is:
turf
'territory so to speak' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for turf that I've seen before include "Piece of lawn" , "manor" , "Surface layer of ground matted with grass" , "Some 19 dn; chuck (out)" , "Personal territory; sod" .)
