Where they try putting you in course (10)
I believe the answer is:
courthouse
'where they try' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'you in course' is the wordplay.
'you' becomes 'thou' (historical second person pronoun).
'in' indicates putting letters inside.
'thou' going within 'course' is 'COURTHOUSE'.
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for courthouse that I've seen before include "suits here?" , "where the action takes place" , "government building" .)
