Initiator of a reception (5)
I believe the answer is:
donor
'initiator' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'a reception' is the wordplay.
I cannot really see how this works, but
'reception' could be 'do' (I've seen this in other clues) and 'do' is located in the answer.
The remaining letters 'nor' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for donor that I've seen before include "blessed person, relatively" , "Philanthropist" , "Almsgiver, benefactor" , "One who dishes out" , "A giver, perhaps of blood" .)
