Tinker picked up award for achievement (5)
I believe the answer is:
medal
'award for achievement' is the definition.
(I've seen this before)
'tinker picked up' is the wordplay.
'tinker' becomes 'meddle' (I've seen this before).
'picked up' shows a homophone (sound like).
'meddle' sounds like 'MEDAL'.
(Other definitions for medal that I've seen before include "Lamed for a gong" , "Coin-like reward for merit" , "Religious or commemorative pin" , "silver?" , "Gong (sl.)" .)
