Definition:Conditional/Antecedent

Definition
Let $P = a \circ b$ be an expression.

The term $a$ is known as the antecedent of $P$.

Linguistic Note
The word antecedent is usually found in classical mathematical literature, notably Euclid's.

It is also frequently used in the context of logic to mean the first term in a conditional statement.

The word comes from the Greek, and literally means leading term.

It is pronounced an-tee-see-dent.
