Teacher organising a tour around central Austria (5)
I believe the answer is:
tutor
'teacher' is the definition.
(tutor is a kind of teacher)
'organising a tour around central austria' is the wordplay.
'organising' indicates anagramming the letters.
'around' indicates putting letters inside.
'central' indicates the central letters.
The middle of 'austria' is 't'.
'tour' is an anagram of 'tuor'.
'tuor' enclosing 't' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "Trout (anag)" , "train" , "Mentor" , "Individual teacher" , "trainer" .)
