Any particle that has odd-half-integer (1/2, 3/2, ...) intrinsic angular momentum (spin), measured in units of . As a consequence of this peculiar angular momentum, fermions obey a rule called the Pau [..]

The term for a particle with half-integer spin. Examples include the quarks and leptons of the Standard Model.

A matter particle. Leptons (such as the electron and neutrinos) and quarksare fermions.Definitions

(particles) A particle with totally antisymmetric composite quantum states, which means they must obey the Pauli exclusion principle, and that obey Fermi-Dirac statistics. They have half-integer spin. [..]

(n) any particle that obeys Fermi-Dirac statistics and is subject to the Pauli exclusion principle

Generic term for any particle with half—integer spin values (1/2, 3/2…etc.), such as the electron, or muon (Martin).
