Guatemalan

The word 'Guatemalan' is a demonym formed by adding the English adjectival suffix '-an' to the place name 'Guatemala.' The origin of 'Guatemala' itself is debated but is widely believed to derive from the Nahuatl word 'Cuauhtēmallān,' meaning "land of many trees," which was the name used by the Nahuatl-speaking Tlaxcalan allies of the Spanish conquistadors. The suffix '-an,' of Latin origin via French, is a common pattern for forming adjectives and nouns denoting origin or affiliation (e.g., American, Mexican). Thus, 'Guatemalan' linguistically marks a direct connection to the territory named by the indigenous Nahuatl language, filtered through Spanish and then adapted into English.

This is a toponymic adjective/noun derived from the country name "Guatemala." It is not productively segmented into smaller, meaningful morphemes in modern English.
