Altlang 

An alternative language; a type of constructed language that predicts the outcome of a certain alternative history.

Wenedyck is perhaps the most well known altlang; it is imagines what the language of the Polish nation would be like if their ancestors had spoken to each other in vulgar Latin.

Artlang 

An Artistic Language. A subset of constructed languages that are devised principally for the purpose of creative expression.

These include "Fictional Languages", which are for the usage of fictional people but are themselves learnable in the real world like Klingon, Quenya and High Valyrian.

There are also languages that themselves are constructed to be used, at least partially, as the medium of expression like Trollsprak, Lingua Romana and the IS language

Artlangs can be considered a neat way of making your world building truly immersive but they could also be seen as really patting the light bulb.
