Fusion of ethnic cultures and languages

If humans coexist alongside races such as ogres and dwarfs at the borders of cities or countries, linguistic and cultural fusion may occur. This could lead to the development of hybrid languages or dialects, blending elements from human languages with those of the other races, and vice versa. Such interactions would likely be localized, occurring primarily in border regions where these groups frequently interact.

The spread and generalization of such hybrid languages across entire cities or countries would be minimal without intentional efforts. However, their influence could be encouraged or controlled through policies or tools aimed at either promoting or preventing linguistic blending. These measures could also facilitate diplomatic relations and trade, especially by providing mechanisms to aid communication between different groups.
