Picked up, boy getting lift (6)
I believe the answer is:
fillip
'lift' is the definition.
(a fillip is a boost or lift)
I don't understand how the remainder of the clue works.
(Other definitions for fillip that I've seen before include "Stimulus, quick boost" , "As tonic" , "Encouraging boost" , "Sharp stimulus or flick of a finger" , "shot in the arm" .)
