Conlangs are typically regarded as playthings for the uncoolest possible variety of nerd. J.R.R. Tolkien referred to conlanging as his “secret vice.” It would not score you points in a typical happy hour anywhere from London to Los Angeles to admit to learning a conlang, or — much worse — creating one yourself. Many people have a sense that the loss of a natural language is something poignant — at least as regrettable, perhaps, as the extinction of a species of small frog whose ecological niche would nevertheless be easily filled by one of his amphibian brethren. But nobody seems to think that constructing a language is like bioengineering a species of frog de novo as a living, hopping, ribbiting part of the human cognitive ecosystem. The more common view is that conlangs are either exercises in comically failed utopianism (Esperanto’s sad and somewhat unfair fate in public opinion), or embarrassing frivolities, like an over-zealous passion for cosplay. But I believe conlangs do represent new linguistic diversity in some significant senses. Some of them much more so than others.
