What is the official language of Guatemala?

Dalia, Guatemala's 20+ Mayan languages are not dialects, they are separate languages. Garifuna and Xinca are non-Mayan languages. It may seem odd for such a small country to have so many, but people are separated by mountains, etc. One of the Mayan languages has a million speakers.

In the USA, instructions and directions are written in Spanish along with the English language now.

Are those dialects only mayans?

Wowwww...amazing!!
