Characteristically agree over variable graphic (9)
I believe the answer is:
typically
'characteristically' is the definition.
(I've seen this before)
'agree over variable graphic' is the wordplay.
I cannot quite understand how this works, but
'over' could be 'all' (synonyms) and 'all' is found within the answer.
'variable' could be 'y' (algebra) and 'y' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for typically that I've seen before include "Characteristically" , "In characteristic style" , "As a characteristic example" , "Ordinarily" .)
