Question latest piercing way to look like Clint Eastwood? (6)
I believe the answer is:
squint
This clue could be a double definition.
'question latest piercing way' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'look like clint eastwood?' is the second definition.
(I've seen this in another clue)
'to' acts as a link.
Can you help me to learn more?
(Other definitions for squint that I've seen before include "Look with eyes turned sideways or half-shut" , "Partly close one's eyes" , "Have a problem seeing" , "Glance obliquely" , "Peer through narrowed eyes" .)
