Left and got picked up (7)
I believe the answer is:
learned
'picked up' is the definition.
('learn' can be a synonym of 'pick up')
'left and got' is the wordplay.
'left' becomes 'L' (common abbreviation).
'and' says to put letters next to each other.
'got' becomes 'earned' (earning is a kind of getting).
'l'+'earned'='LEARNED'
(Other definitions for learned that I've seen before include "Knowledgeable - scholarly" , "Highly educated" , "Came to know" , "Discovered, ascertained" , "Highbrow" .)
