Hadronic

Part of speech: adjective

Definitions

1. Relating to or characteristic of particles that interact via the strong nuclear force, particularly those made up of quarks such as protons and neutrons, often studied in particle physics
2. Concerning the class of subatomic particles that experience the strong interaction, including composite particles like baryons and mesons, significant in nuclear and particle physics contexts
3. Pertaining to the properties or behaviors of strongly interacting particles composed of quarks, central to the study of fundamental forces and matter structure in physics

Etymology: The adjective "hadronic" is built directly from "hadron," a coinage of the physicist Lev Okun in 1962, which is itself the modern formation that needs unpacking. "Hadron" draws on the Ancient Greek "hadrós," meaning "thick," "bulky" or "stout," chosen because hadrons are the particles that feel the strong force, the force that binds the nucleus together and that the word's makers intended to contrast with the lighter, weaker-interacting "leptons," from Greek "leptós," "thin" or "fine." The ending "-ic" comes from Latin "-icus," which passed into English through Old French "-ique" and Middle English "-ik," and attached to "hadron" to give an adjective meaning "relating to or consisting of hadrons." The same suffix appears in words like "electric," which descends from Greek "ēlektron," "amber," through Latin "ēlectrum" and "electricus."
