Coach tour rearranged to take in Turkey's capital (5)
I believe the answer is:
tutor
'coach' is the definition.
('tutor' can be a synonym of 'coach')
'tour rearranged to take in turkey's capital' is the wordplay.
'rearranged' indicates an anagram.
'to take in' is an insertion indicator.
'capital' suggests taking the first letters.
The initial letter of 'turkeys' is 't'.
'tour' with letters rearranged gives 'tuor'.
'tuor' going around 't' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "Private or university teacher" , "Coach, teacher" , "Private instructor" , "He shows us the way" , "Master" .)
