seepage

I'm a little stuck... Click here to teach me more about this clue!

'leak you' is the definition.
'seepage' can be an answer for 'leak' (thesaurus). I'm unsure of the 'you' bit.

'understand to the paper' is the wordplay.
'understand' becomes 'see' ('see' can be a synonym of 'understand').
'to the paper' becomes 'page' (page is a kind of paper**).
'see'+'page'='SEEPAGE'

Can you help me to learn more?

(Other definitions for seepage that I've seen before include "Slow flow of fluid" , "Leaking liquid" , "Ooze" , "running out slowly" , "problem with tank" .)
