Coach tour rearranged around end of August (5)
I believe the answer is:
tutor
'coach' is the definition.
('tutor' can be a synonym of 'coach')
'tour rearranged around end of august' is the wordplay.
'rearranged' indicates an anagram.
'around' means one lot of letters goes inside another.
'end of' indicates one should take the final letters.
The final letter of 'august' is 't'.
'tour' anagrammed gives 'tuor'.
'tuor' going around 't' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "Master" , "Give individual instruction" , "Coach, teacher" , "Guardian" , "trainer" .)
