For questions, do exams (8)
I believe the answer is:
contests
'for questions' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'do exams' is the wordplay.
'do' becomes 'con' (both can mean to defraud).
'exams' becomes 'tests' ('test' can be a synonym of 'exam').
'con'+'tests'='CONTESTS'
Can you help me to learn more?
(Other definitions for contests that I've seen before include "Disputes; competitions" , "sporting events?" , "Struggles between rivals" , "Competitions between rivals" , "Competitions, struggles" .)
