Naturalistic artlang

A naturalist artlang is an artlang that is designed to resemble a natlang. A good naturalist artlang has a grammar as complex as grammars of natlangs and avoids unnatural features such as self-segregating morphology. Famous examples of naturalist artlangs are Quenya, Sindarin, Brithenig and Verdurian. Many naturalist artlangs come with a fictional history and an elaborated conculture associated with it; some conlangers create entire families of interrelated naturalist artlangs.
