Stray order from a deity (5)
I believe the answer is:
satyr
'a deity' is the definition.
(I know that satyr is a type of Greek deity)
'stray order' is the wordplay.
'order' indicates an anagram.
'stray' is an anagram of 'SATYR'.
'from' acts as a link.
(Other definitions for satyr that I've seen before include "Pan maybe" , "Mythical woodland god or grossly lustful man" , "Mythological woodland deity" , "Goatlike deity of Greek myth" , "Classical deity" .)
