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' means one lot of letters go next to another.
'returning' shows that the letters should be reversed in order.
'to clear' becomes 'rid' (synonyms).
'rid' in reverse letter order is '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" .)
