Definition

A contradiction is also known as:

a logical falsehood or logical falsity
a contravalid proposition
an absurdity or absurdism, as the idea of a statement being both false and true at once is absurd.

Also seen:

an inconsistency
an unsatisfiable formula.

However, on $\mathsf{Pr} \infty \mathsf{fWiki}$, these terms are reserved for the analogous concepts for proof systems and formal semantics respectively.
