This is a list of Latin words with derivatives in English language. Ancient orthography did not distinguish between i and j or between u and v. [1] Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words.

For example, for visible light, the refractive index of glass is typically around 1.5, meaning that light in glass travels at c / 1.5 ≈ 200 000 km/s (124 000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in air is about 90 km/s (56 mi/s) slower than c.
Speed of light, celeritas; Celerity Computing Inc., defunct San Diego, California vendor; Celerity IT, a Virginia-based web development consulting group; Phase velocity, speed of propagation of a wave; Proper velocity, an alternative way of measuring motion in relativity
Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.
The speed of light in vacuum is defined to be exactly 299 792 458 m/s (approximately 186,282 miles per second). The fixed value of the speed of light in SI units results from the fact that the metre is now defined in terms of the speed of light. All forms of electromagnetic radiation move at exactly this same speed in vacuum.
The following is an alphabetical list of Greek and Latin roots, stems, and prefixes commonly used in the English language from P to Z. See also the lists from A to G and from H to O . Some of those used in medicine and medical technology are not listed here but instead in the entry for List of medical roots, suffixes and prefixes .
Translated into Latin from Baudelaire's L'art pour l'art. Motto of Metro-Goldwyn-Mayer. While symmetrical for the logo of MGM, the better word order in Latin is "Ars artis gratia". ars longa, vita brevis: art is long, life is short: Seneca, De Brevitate Vitae, 1.1, translating a phrase of Hippocrates that is often used out of context. The "art ...
He could moreover prove that in a vacuum such a wave would travel at the speed of light, and thus light itself was a form of electromagnetic radiation. Maxwell's equations, which unify light, fields, and charge are one of the great milestones of theoretical physics. [25]: 696–700
