Financial backers in good spirits (6)
I believe the answer is:
angels
This might be a double definition.
'financial backers' is the first definition.
(I've seen this in another clue)
'good spirits' is the second definition.
'angels' can be an answer for 'spirits' (I've seen this before). I'm not certain of the 'good' bit.
'in' is the link.
Can you help me to learn more?
(Other definitions for angels that I've seen before include "Gleans that they're heavenly" , "See 13" , "Financial backers, esp theatrical" , "Spiritual beings" , "Cherubim, seraphim etc" .)
