Teacher's out working in Turkey (5)
I believe the answer is:
tutor
'teacher's' is the definition.
(I know this)
'out working in turkey' is the wordplay.
'working' indicates an anagram.
'in' indicates putting letters inside.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'out' with letters rearranged gives 'uto'.
'uto' placed inside 'tr' is 'TUTOR'.
(Other definitions for tutor that I've seen before include "He shows us the way" , "Coach, teacher" , "Personal teacher" , "Edify" , "Private educator" .)
