Etymology
The term is a modern scientific compound. The first element, "matter," originates from Latin materia, meaning the physical stuff from which things are made, derived from mater (mother) in the sense of "source" or "origin." The prefix "anti-," from Greek, signifies opposition. The compound "antimatter" was coined in the early 20th century following theoretical predictions of particles with identical mass but opposite charge to ordinary particles. Thus, "matter-antimatter" juxtaposes the two opposing forms of substance, encapsulating the fundamental duality and mutual annihilation that defines their relationship in particle physics.

matter: From Latin materia (substance, material). Functional role: The core noun denoting physical substance.
anti: From Greek anti (against, opposite). Functional role: A prefix indicating opposition or contrast.
matter: From Latin materia (substance, material). Functional role: The core noun denoting physical substance, repeated to form the compound.
Examples
