Panhandle (3)

'panhandle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for beg that I've seen before include "Earnestly entreat" , "Get by any means - . . ., borrow or steal" , "Plead or ask for alms" , "Plead or importune" , "Implore, solicit" .)
