It's blind, dear (4)
I believe the answer is:
love
'dear' is the definition.
(I know that dear can be written as love)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for love that I've seen before include "affair? On the contrary" , "Vole (anag.)" , "like very much?" , "Ardent emotion" , "See 10" .)
