== English == === Etymology === Coined by Italian physicist Enrico Fermi in 1933 from neutron + the Italian diminutive suffix -ino; by surface analysis, neutr(o)- +‎ -ino. === Pronunciation === (UK) IPA(key): /njuːˈtɹiːnəʊ/ (General American) IPA(key): /nuˈtɹinoʊ/ Rhymes: -iːnəʊ Hyphenation: neu‧tri‧no === Noun === neutrino (plural neutrinos) An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect. ==== Derived terms ==== ==== Related terms ==== ==== Translations ==== == Czech == === Pronunciation === IPA(key): [ˈnɛu̯triːno] === Noun === neutrino n (physics) neutrino ==== Declension ==== == Dutch == === Pronunciation === === Noun === neutrino n (plural neutrino's, no diminutive) (physics) neutrino == French == === Pronunciation === IPA(key): /nø.tʁi.no/ === Noun === neutrino m (plural neutrinos) (physics) neutrino === Further reading === “neutrino”, in Trésor de la langue française informatisé [Digitized Treasury of the French Language], 2012 == Galician == === Noun === neutrino m (plural neutrinos) (physics) neutrino == Ido == === Noun === neutrino (plural neutrini) (physics) neutrino == Italian == === Etymology === Borrowed from English neutrino. === Noun === neutrino m (plural neutrini) (physics) neutrino == Northern Sami == === Etymology === (This etymology is missing or incomplete.
