Elnath/Origin

Origin
Beta Tauri is the second brightest star in the constellation Taurus, with an apparent magnitude of 1.68. Ptolemy considered Beta Tauri to be shared by Auriga, and Bayer assigned it a designation in both constellations: Beta Tauri (β Tau) and Gamma Aurigae (γ Aur). When the modern constellation boundaries were fixed in 1930, the latter designation dropped from use. The star has the traditional name Elnath—a reference to "the butting" of the bull's horns. Beta Tauri has the traditional name Elnath, El Nath, or Alnath, which comes from the Arabic word النطح an-naţħ, meaning "the butting" (i.e. the bull's horns). As in many other (but not all) Arabic star names, the article ال is transliterated literally as el, despite the fact that in Arabic pronunciation it is assimilated to the following n; it can also be omitted: Nath.
