Constructed Languages (ConLangs)

Rick Harrison's FAQ had a good description of constructed/artificial languages:

An artificial language is a language that has been deliberately designed by one person or a small group of people over a relatively short period of time. Synonyms for the term artificial language include planned language, constructed language, model language, and invented language. Artificial languages designed for specific purposes are also known by an array of other terms. Those used in works of fiction are called imaginary languages or fictional languages. Those designed to facilitate global communications are called universal languages, auxiliary languages (auxlangs), interlanguages or interlinguas, international languages, etc. The realm of artificial languages also includes logical languages, number languages, symbolic languages a.k.a. icon(ic) languages, and pasimologies (gesture languages).

Some of these languages have had more visibility than others: Esperanto, Star Trek's Klingon, Tolkien's Quenya, Lojban, and Volapük are some examples.
