Egyptian god, determined (3)
I believe the answer is:
I believe this is a double definition.
'egyptian god' is the first definition.
(Set is an example)
'determined' is the second definition.
(similar in meaning)
(Other definitions for set that I've seen before include "Put, coagulate", "become firm", "'Put, place or fix in position (3)'", "Place - become rigid - adjust - group of tennis games - fixed - clique - fall beneath the horizon", "exclusive party".)
