'through?' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?

'from a large number might a quarter' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'large number' becomes 'm'.
'might a quarter' becomes 'ny' (I am not sure about this - if you are sure you should believe this answer much more).
'a'+'m'='am'
'am' with letters rearranged gives 'ma'.
'ma'+'ny'='MANY'

'get' is the link.
