Instructor arranging a tour around central Austria (5)
I believe the answer is:
tutor
'instructor' is the definition.
(I know that tutor is a type of instructor)
'arranging a tour around central austria' is the wordplay.
'arranging' indicates an anagram.
'around' indicates putting letters inside.
'central' indicates the central letters.
The middle of 'austria' is 't'.
'tour' with letters rearranged gives 'tuor'.
'tuor' going around 't' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "Master" , "Teach" , "Private or university teacher" , "college teacher" , "Private educator" .)
