Webster's Revised Unabridged Dictionary
    • n Esperanto An artificial language, intended to be universal, devised by Dr. Zamenhof, a Russian, who adopted the pseudonym “Dr. Esperanto” in publishing his first pamphlet regarding it in 1887. The vocabulary is very largely based upon words common to the chief European languages, and sounds peculiar to any one language are eliminated. The spelling is phonetic, and the accent (stress) is always on the penult. A revised and simplified form, called Ido was developed in 1907, but Esperanto remained at the end of the 20th century the most popular aritficial language designed for normal human linguistic communication.

Century Dictionary and Cyclopedia
    • n Esperanto The name of a recent ‘universal language’ constructed, like Volapük, by arbitrary reduction and manipulation of words and forms taken from existing European languages, and the adoption of a simple and regular inflection. The general aspect of the language as printed is that of a shrunken composite of Latin, Spanish, and French, with a Polynesian spelling.
