Public relations in place? That's the spirit! (6)
I believe the answer is:
sprite
'the spirit' is the definition.
(thesaurus)
'public relations in place?' is the wordplay.
'public relations' becomes 'PR' (abbreviation).
'in' is an insertion indicator.
'place?' becomes 'site' (synonyms).
'pr' put within 'site' is 'SPRITE'.
'that's' acts as a link.
(Other definitions for sprite that I've seen before include "Pet, sir, could be a goblin" , "water pixie" , "Puck, say" , "Supernatural being" , "Dainty type" .)
