discover

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

'find' is the definition.
('discover' can be a synonym of 'find')

'compact excessively' is the wordplay.
'compact' becomes 'disc' (I can't justify this - if you can you should believe this answer much more).
'excessively' becomes 'over'.
'disc'+'over'='DISCOVER'

'something' is the link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for discover that I've seen before include "Make a new finding" , "Be the first to find or see" , "Be the first to have sight or knowledge of" , "Detect, find" , "Uncover, find" .)
