Ernesto now carrying weight (3)
I believe the answer is:
ton
'weight' is the definition.
(unit of weight)
'ernesto now carrying' is the wordplay.
'carrying' indicates a hidden word.
'TON' is hidden in the letters of 'ernesto now'.
(Other definitions for ton that I've seen before include "2,240 lbs" , "U nit of weight" , "Heavy weight or 100mph" , "Two thousand - two hundred and forty pounds" , "Twenty cwt" .)
