null

This term carries a heavy connotation of absolute negation or total absence. In legal contexts, it is almost exclusively paired with void to describe a contract or agreement that is treated as if it never existed, stripping it of all authority and binding power.

In technical and mathematical fields, it represents a specific state of non-existence rather than just the number zero. In computing, a null value is a marker indicating that data is missing or undefined, distinguishing a deliberate lack of value from a numerical zero.
