How to Use Conlangs in D&D

Conlang is a great way to add some verus millitude into the world. It's not about whether your players are okay with it, but how that interaction has been scaffolded. The way I like to figure it is basically your players should be able to do whatever their characters are able to do effortlessly. However, if it should take their characters effort, then you should make it effortful unless that part of it isn't fun in which case you can just be shunted off.
