Extended hunger? (4)
I believe the answer is:
long
I believe this is a double definition.
'extended' is the first definition.
(extended can mean longer than usual)
'hunger?' is the second definition.
(both can mean to crave)
(Other definitions for long that I've seen before include "Thus having been treated by stretcher, perhaps" , "extended period" , "Lengthy - pine" , "Really want" , "Yearn (for)" .)
