null
Absence as value
Null can function as an adjective, noun, or verb, with the idea of zero or nothing central to its meaning.
A null hypothesis, for example, is one where data is insignificant.
In math, a null set is a one that contains no members.
The phrase null and void, popular in law, means without valid legal effect.
As a noun, null means zero.
If something is nulled it is cancelled, set to zero, or made ineffective.
Null is related to nil; the two words overlap considerably in meaning.
