Woman about to receive priest (5)
I believe the answer is:
celia
'woman' is the definition.
'about to receive priest' is the wordplay.
'about to' becomes 'ca' (I've seen this in other clues).
'receive' indicates putting letters inside.
'priest' becomes 'eli' (I've seen this before).
'ca' placed around 'eli' is 'CELIA'.
(Other definitions for celia that I've seen before include "Rosalind's cousin" , "Frederick's daughter" , "Character in Tales from Shakespeare" , "Daughter to Frederick" , "lady" .)
