Oral tests in European subjects (6)
I believe the answer is:
czechs
'european subjects' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'oral tests' is the wordplay.
'oral' shows a homophone (sound like) (how it sounds when spoken).
'tests' becomes 'checks' ('check' can be a synonym of 'test').
'checks' is a homophone of 'CZECHS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for czechs that I've seen before include "Slavs" , "Nationality of citizens of Prague" , "Citizens of a republic" , "Eg, Prague natives" .)
