Teacher runs with class in Yorkshire town (9)
I believe the answer is:
doncaster
'yorkshire town' is the definition.
'doncaster' can be an answer for 'town' (I've seen this before). I am not certain of the 'yorkshire' bit.
'teacher runs with class' is the wordplay.
'teacher' becomes 'don' (don can mean an academic - especially at Oxbridge).
'runs' becomes 'r' (cricket abbreviation).
'with' is a charade indicator (letters next to each other).
'class' becomes 'caste' (type of social class).
'r' after 'caste' is 'caster'.
'don'+'caster'='DONCASTER'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for doncaster that I've seen before include "northern town" , "Town of South Yorkshire" .)
