One used to row in bingo, a rascal (3)
I believe the answer is:
oar
'one used to row' is the definition.
(oars are used to row)
'in bingo a rascal' is the wordplay.
'in' indicates a hidden word.
'OAR' is hidden within 'bingo a rascal'.
(Other definitions for oar that I've seen before include "Crew member" , "One of an eight" , "spoon?" , "One paddling" , "Rower's paddle" .)
