Has a craving (6)
I believe the answer is:
yearns
'has a craving' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yearns that I've seen before include "Craves, longs intensely" , "Desires strongly" , "Longs for, pines" , "'Hankers, longs (6)'" , "'Craves, longs for (6)'" .)
