Person directing the team bus? (5)
I believe the answer is:
coach
'bus?' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for coach that I've seen before include "Train the bus" , "Trainer - vehicle" , "Tutor" , "Vehicle - teach(er)" , "Train - or part of one!" .)
