#Alcor

• Alcor — The proper name of a fourth-magnitude star in the constellation Ursa Major (80 Ursae Majoris), located very close to the brighter star Mizar, with which it forms a well-known visual double star pair. Historically, the ability to visually distinguish these two stars with the naked eye was utilized as a classic test for visual acuity across various cultures.
• Alcoran — An obsolete and literary spelling variant for the Quran (the holy scripture of Islam). The term was historically used in European and Romanian cultural spaces, influenced by Western languages, keeping the Arabic definite article incorporated directly into the lexical structure of the word, but its current usage is strictly historical.
