Cordilleras
Aiton's Encyclopedia: a range of mountains. The word is Spanish, meaning originally a cord or rope. It is a general word like plateau, and is used by the Spanish to designate a chain of mountains. As a proper name, the term was first applied by the Spaniards to the ranges of the Andes, and was extended to the ranges of Mexico and farther northward. American geographers are now pretty well agreed to confine the term to the vast mountain system embraced by the Rocky Mountains and the Sierra Nevada. The Cordilleras, taken in this sense, are a thousand miles in width in the latitude of Colorado, and extend from Central America to Alaska. The Coast Range and the Cascades are included.
Collier's New Encyclopedia: a name applied in America to various chains of mountains.

Corinna
Aiton's Encyclopedia: ko-rin'a, a Greek lyric poetess of the first half of the fifth century B. C. She was born at Tanagara, Boeotia, She is said to have instructed Pindar and to have won the victory over him five times in the public poetic contests. According to Pausanius, she was so beautiful that the judges may have been influenced in her favor. Only a few fragments of her poems are extant.
1000 Classical Characters: A celebrated woman of Thebes , whose father was Archelodorus. It is said that she obtained a poetical prize five times against the competitorship of Pindar. 2026 Editor's Note: Corinna was an ancient Greek lyric poet from Tanagra in Boeotia rather than simply a woman of Thebes. Although ancient sources portray her as a contemporary of Pindar who won poetical prizes against him, modern scholars debate her actual dating, with proposed dates ranging from the early fifth century to the late third century BC. Her surviving poetry reworks well-known myths to include details not known from any other sources, focusing on local Boeotian legends. (Ed: BR 2026-06-01)
