Word History

Etymology

borrowed from New Latin, shortened from Arabic al-nasr al-ṭāʼir "the flying eagle," a name for the line of stars Alpha, Beta and Gamma Aquilae

Note: According to Paul Kunitzsch, Arabische Sternnamen in Europa (Wiesbaden, 1959), the Arabic name (with many variants) was applied to the single star Alpha Aquilae for convenience in astrolabe manuals.
