/ˈænˌtaɪˌmædər/,

/ˈæn(t)əˌmædər/

Origin: Formed within English, by derivation. Etymons: anti- prefix, matter n.¹

Etymology: < anti- prefix + matter n.¹

Physics.

Matter consisting of subatomic particles which are the antiparticles of those making up ordinary matter. Cf. antiparticle n.An interaction between matter and its antimatter equivalent can lead to their mutual annihilation and a release of energy. In science fiction contexts such energy is sometimes represented as a source of power for weapons, propulsion systems, etc.In quot. 1898: a hypothetical substance which is gravitationally repelled by ordinary matter.
