See nothing in Manila (3)
I believe the answer is:
nil
'see nothing' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'in manila' is the wordplay.
'in' indicates a hidden word.
'NIL' can be found hidden inside 'manila'.
Can you help me to learn more?
(Other definitions for nil that I've seen before include "Non-existent" , "Nothing - in Latin" , "You get nothing" , "Score of nought" , "0" .)
