Order coach (8)
I believe the answer is:
instruct
This clue is a double definition.
'order' is the first definition.
(I've seen this before)
'coach' is the second definition.
(thesaurus)
(Other definitions for instruct that I've seen before include "Impart skills or knowledge to" , "Coach" , "Give lesson or order to" , "Inform or authorise" , "Direct; teach" .)
