Unable to see Venetian. perhaps (5)
I believe the answer is:
blind
'unable to see' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for blind that I've seen before include "Like a bat" , "how very drunk one is" , "Unable to see - screen" , "Unaware of" , "shade" .)
