Serviceperson’s angry speech with VIP (9)
I believe the answer is:
celebrant
'serviceperson's angry' is the definition.
I can't judge whether this defines the answer.
'speech with vip' is the wordplay.
'speech' becomes 'rant' (rant is a kind of speech).
'with' says to put letters next to each other.
'vip' becomes 'celeb' (I've seen this in another clue).
'rant' after 'celeb' is 'CELEBRANT'.
Can you help me to learn more?
(Other definitions for celebrant that I've seen before include "One performing a rite" , "person performing rite" , "An officiating priest, especially at Eucharist" .)
