"Constructed language (etymology: see language. The verb “construct” is derived from Latin com- “with, together” and struere “to build”)—typically, a language (Einzelsprache) that was constructed by a single person or institution for the purpose of ensuring “neutral” (that is, not connected to a state language or a nation’s language) communication (for instance, Esperanto). To some extent it is a misnomer because all Einzelsprachen (languages) are constructed. The difference is that people tend to believe (wrongly) that national languages and state (official) languages are “natural,” either a product of nature or a divinity’s will. They contrast them to constructed languages that are labelled as “artificial,” meaning “man-made.” But all languages (Einzelsprachen) are man-made. In this context the only natural (biological) element is Ø language.", en: Project Muse, Words in Space and Time, Glossary. p. 9,
