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 an anagram.
'around' means one lot of letters goes inside another.
'central' indicates the central letters.
The middle of 'austria' is 't'.
'tour' is an anagram of 'tuor'.
'tuor' placed around 't' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "Trout (anag)" , "train" , "Mentor" , "Individual teacher" , "trainer" .)
