Entitled man in noisy centre invoking deity (6)
I believe the answer is:
osiris
'deity' is the definition.
(Osiris is an example)
'entitled man in noisy centre' is the wordplay.
'entitled man' becomes 'sir' (sir is a kind of man. I am not sure about the 'entitled' bit.).
'in' indicates putting letters inside.
'centre' says to take the centre.
The middle letters of 'noisy' are 'ois'.
'sir' put inside 'ois' is 'OSIRIS'.
'invoking' acts as a link.
Can you help me to learn more?
(Other definitions for osiris that I've seen before include "Husband of Isis, father of Horus - sis or I (anag)" , "dead judge?" , "Egyptian god, father of Horus" , "Egyptian god of the underworld" , "underworld boss" .)
