Altlang

An altlang is a fictional language set in an alternative history. The most famous altlang (at least in the Internet-based conlanging community) is Andrew Smith's Brithenig, which is set in Ill Bethisad, a collaborative alternative history with, among other changes, a stronger Roman presence in Britain, resulting in the survival of a Romance language in that province.

The word "altlang" was first used in this sense by James Landau in 2003.

A related concept is the lostlang, which exists in a version of the real world with just a few extra languages added.
