Worked notice after returning to clear order (9)
I believe the answer is:
direction
'order' is the definition.
(thesaurus)
'worked notice after returning to clear' is the wordplay.
'worked' is an anagram indicator.
'after' says to put letters next to each other.
'returning' says the letters should be written in reverse.
'to clear' becomes 'rid' (synonyms).
'rid' reversed gives 'dir'.
'notice' anagrammed gives 'ection'.
'ection' after 'dir' is 'DIRECTION'.
(Other definitions for direction that I've seen before include "Administration" , "Guidance" , "Tenor" , "The way in which something is moving" , "Command" .)
