Hollow-eyed hawk (7)
I believe the answer is:
haggard
'hollow-eyed' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for haggard that I've seen before include "Careworn - novelist" , "Looking exhausted and unwell" , "Farm building for storing crops" , "She came from him" , "Rider" .)
