Good landlord provides spirit (5)
I believe the answer is:
ghost
'spirit' is the definition.
(ghost is a kind of spirit)
'good landlord' is the wordplay.
'good' becomes 'g' (abbreviation).
'landlord' becomes 'host'.
'g'+'host'='GHOST'
'provides' is the link.
(Other definitions for ghost that I've seen before include "Apparition; faint trace" , "suggestion" , "A spirit from the beyond" , "Phantom" , "Write for another" .)
