Implore, plead (3)
I believe the answer is:
beg
I believe this is a double definition.
'implore' is the first definition.
(I know that implore can be written as beg)
'plead' is the second definition.
(I know that beg is a more specific form of plead)
(Other definitions for beg that I've seen before include "Get by any means - . . ., borrow or steal" , "Earnestly entreat" , "Beseech or ask for charity" , "Plead or scrounge" , "Ask humbly" .)
