Welcomed by minstrel, earnings pick up again (7)
I believe the answer is:
relearn
'pick up again' is the definition.
('learn' can be a synonym for 'pick up' so perhaps 'relearn' is OK for 'pick up again')
'welcomed by minstrel earnings' is the wordplay.
'welcomed by' says the answer is hidden in the clue.
'RELEARN' can be found hidden inside 'minstrel earnings'.
(Other definitions for relearn that I've seen before include "Once again master" , "Get to know again" , "Come to know something again" , "Recommit to memory" , "Mug up once more" .)
