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