Board and lodging for priest in the Underworld (9)
I believe the answer is:
directors
'board' is the definition.
(thesaurus)
'priest in the underworld' is the wordplay.
'priest' becomes 'rector' (I've seen this before).
'in the' indicates putting letters inside.
'underworld' becomes 'dis' (underworld in classical mythology).
'rector' inserted into 'dis' is 'DIRECTORS'.
'and lodging for' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for directors that I've seen before include "they lead the way" , "Board members" , "Businessmen" , "Those managing" , "who make cuts" .)
