Form of verb is beyond many English (4,5)
I believe the answer is:
past tense
'form of verb' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'beyond many english' is the wordplay.
'beyond' becomes 'past' (to go beyond something is to go past it).
'many english' becomes 'tense' (I can't justify this - if you can you should give a lot more credence to this answer).
'past'+'tense'='PAST TENSE'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for past tense that I've seen before include "Grammatical verb form" , "It expresses something that has happened" , "Form of verb showing that the action has already happened" , "history?" , "What could be perfect in a lesson of French" .)
