A month of possibility (3)
I believe the answer is:
may
This could be a double definition.
'a month' is the first definition.
(May is an example)
'possibility' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'of' is the link.
Can you help me to learn more?
(Other definitions for may that I've seen before include "'5 _____' (popular piece of music by Bach)" , "The merry merry month( 3)" , "Might" , "Month; hawthorn" , "Fifth month" .)
