Praise work I abandoned, taken on by former partner (5)
I believe the answer is:
extol
'praise' is the definition.
(extolling is a kind of praising)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for extol that I've seen before include "be lavish with praise" , "Acclaim" , "Speak highly" , "Warmly approve of" , "Cry up" .)
