American Heritage® Dictionary of the English Language, Fourth Edition
- n. Any of a family of elementary particles that participate in the weak interaction, including the electron, the muon, and their associated neutrinos. See Table at subatomic particle.
Century Dictionary and Cyclopedia
- n. The smallest coin of modern Greece, equal to a centime. One hundred lepta make a drachma.
- n. The typical genus of Leptonidæ. The shell resembles that of Kellia, is often minutely punctured, and has divergent teeth. There are many species. L. squamosum and L. convexum are British.
Wiktionary
- n. A small, bronze Judean coin from the 1st century BC. The lowest value coin ever in circulation. Considered by some to be the widow's mite.
- n. An elementary particle with a spin of 1/2 (a fermion) which is immune to the strong nuclear force (including the electron, the muon, the neutrino and the tauon).
GNU Webster's 1913
- n. (Physics) an elementary particle that participates in weak interactions but does not participate in the strong interaction; it has a baryon number of 0. Some known leptons are the electron, the negative muon, the tau-minus particle, and the neutrinos associated with each of these particles.

- n. an elementary particle that participates in weak interactions; has a baryon number of 0
- n. 100 lepta equal 1 drachma in Greece
Etymologies
- From Ancient Greek λεπτόν (lepton), neuter form of λεπτός (leptos, "small"). (Wiktionary)
- lepto- + -on1. (American Heritage® Dictionary of the English Language, Fourth Edition)
Examples
“The best known lepton is the electron; the other five are the muon, the tau particle, and three matching neutrinos.”
“The coin was called a lepton and it took one hundred of them to make a denarius—an average day’s wage for a laborer.”
“Contraction of minute, from the Latin minutum, the translation of the Greek word lepton, the very smallest bronze of copper coin (Luke 12: 59; 21: 2).”
“Also there is six kind of lepton, that is electron (e), muon (µ), tau (t), neutrino-electron (?”
“These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons.”
“The chamber permitted particles to be tracked with a precision of better than 1mm, as a result of which several novel ephemeral subatomic particles have been discovered, such as the tau-lepton – a heavy version of the electron – and exotic varieties of quarks.”
“We started uttering other unknown words, like muon, lepton, and hadron.”

“Then in 1980, Father Francis Filas of Loyola University in Chicago, a Jesuit like our Father Morelli here, and Michael Marx, an expert in classical coins, identified the object over the right eye as a Julia lepton coin with a distinctive design of a sheaf of barley.”
“The lepton with the distinctive barley sheaf design was minted only once, in 29 A.D. Putting coins on the eyes of the dead has a long history in the Middle East.”
“So, if were seeing more leptons and missing pt than expected coming from decays, maybe its because they have some other intermediate decay channel, like a charged Higgs, or something totally weird like a half-quark/half-lepton thing called a leptoquark.”
