Teach where the pupils are? (6)
I believe the answer is:
inform
'teach' is the definition.
(thesaurus)
'the pupils are?' is the wordplay.
I cannot really see how this works, but
'pupils' could be 'form' (class of school pupils) and 'form' is found in the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'where' is the link.
Can you help me to learn more?
(Other definitions for inform that I've seen before include "Grass - doing well" , "Enlighten" , "Apprise: grass!" , "Brief" , "Impart knowledge" .)
