Game show host to interrogate teacher (8,6)
I believe the answer is:
question master
'game show host' is the definition.
'question master' can be an answer for 'host' (question master is a kind of host). I'm not sure about the 'game show' bit.
'interrogate teacher' is the wordplay.
'interrogate' becomes 'question' (synonyms).
'teacher' becomes 'master' (I've seen this before).
'question'+'master'='QUESTION-MASTER'
'to' is the link.
Can you help me to learn more?
(Other definitions for question master that I've seen before include "Quiz show host" , "Quiz compere" , "game host" .)
