squalor

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

'endless filth' is the definition.
'squalor' can be an answer for 'filth' (I've seen this in another clue). I'm not certain of the 'endless' bit.

'most of team learning' is the wordplay.
'most of' means to remove the last letter.
'team' becomes 'squad' (sports team).
'learning' becomes 'lor' (I can't justify this - if you can you should give a lot more credence to this answer).
'squad' with its final letter taken away is 'squa'.
'squa'+'lor'='SQUALOR'

Can you help me to learn more?

(Other definitions for squalor that I've seen before include "Filthiness" , "State of poverty and neglect" , "What could be filthy" , "Sleaziness, mean poverty" , "Sordid dirtiness" .)
