Deity really turned against most people from Ireland (6)
I believe the answer is:
osiris
'deity' is the definition.
(Osiris is an example)
'really turned against most people from ireland' is the wordplay.
I cannot really see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
'ireland' could be 'ir' (abbreviation for Ireland) and 'ir' is located in the answer.
The remaining letters 'sis' 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).
Can you help me to learn more?
(Other definitions for osiris that I've seen before include "Egyptian god, father of Horus" , "Egyptian god of the underworld" , "Husband of Isis, father of Horus - sis or I (anag)" , "once highly esteemed by Egyptians" , "one Egyptians worshipped" .)
