1. (physics) Matter that is composed of the antiparticles of those that constitute normal matter.
   • 2023 September 27, Hannah Devlin, “Scientists find antimatter is subject to gravity”, in The Guardian‎^[1], →ISSN:

     But most theories predict that equal amounts of matter and antimatter should have been produced during the big bang, and the mystery of what happened to all the antimatter is a central question in fundamental physics.

2. (physics) A form of matter that has a key property, such as charge, opposite to that of ordinary matter.
   • 2010 November 19, Alok Jha, “We can't see antimatter but it really does matter”, in The Guardian‎^[2], →ISSN:
