What one must do to get product like tissues? (8)
I believe the answer is:
multiply
'what' is the definition.
Both the answer and definition are adverbs.
Maybe there's an association between them I don't understand?
'one must do to get product like tissues?' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'do' could be 'ply' (plying is a kind of doing) and 'ply' 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 multiply that I've seen before include "Increase the number" , "Accumulate" , "in several ways, each with its own stress" , "Increase, procreate" , "Add an amount to itself a number of times" .)
