Scott (Yvain) did this in his fictional world. For example:

• Assertions require probability statements. There’s no grammatically correct way to say “The dog is in the blue house” without adding some modifier for how certain you are of this (probably along the lines of “tautologous, near-certain, probably true, uncertain, probably false, near-certainly false). There is also the option of elegantly expressing particular numerical possibilities.

• Assertions about plurals require quantifiers. For example, it’s ungrammatical to say “Atheists break the law”. One has to clarify this by adding “all”, “most”, “at least one”, “a disproportionate number”, etc. It’s pretty hard to stereotype in Kadhamic without meaning it.
