Good landlords providing spirits (6)
I believe the answer is:
ghosts
'spirits' is the definition.
(I know this)
'good landlords' is the wordplay.
'good' becomes 'g' (abbreviation).
'landlords' becomes 'hosts' (I've seen this before).
'g'+'hosts'='GHOSTS'
'providing' acts as a link.
(Other definitions for ghosts that I've seen before include "Spooks, spectres" , "Spectres, wraiths" , "Apparitions of a dead people" , "Writes for another; Ibsen play" , "Spirits or apparitions" .)
