Challenges pictures lacking flash (4)
I believe the answer is:
vies
This clue could be a double definition.
'challenges' is the first definition.
Although both the answer and definition are verbs in their -s form, I cannot see how one could define the other.
'pictures lacking flash' is the second definition.
Although both the answer and definition are verbs in their -s form, I don't see how one could define the other.
Can you help me to learn more?
(Other definitions for vies that I've seen before include "Strives with, rivals" , "Competes, carries on rivalry" , "Struggles" , "Contends" .)
