Crave, desire (5)
I believe the answer is:
I believe this clue is a double definition.
'crave' is the first definition.
(I've seen this before)
'desire' is the second definition.
(I know that yearn is a more specific form of the action hanker)
(Other definitions for yearn that I've seen before include "Have a great longing" , "Have an intense feeling of longing" , "Pant - pine" , "Long (for something)" , "Feel desire" .)
