'does it make' is the definition.
I can't tell whether this definition defines the answer.

'arran wet distributed round island?' is the wordplay.
'distributed' indicates anagramming the letters.
'round' is an insertion indicator.
'island?' becomes 'i' (geographical abbreviation).
'arran'+'wet'='arranwet'
'arranwet' anagrammed gives 'ranwater'.
'ranwater' placed around 'i' is 'RAINWATER'.
