The Spanish word 'mexicano' (meaning 'Mexican') comes from combining 'México' with the suffix '-ano', which indicates origin or belonging. The name 'México' itself can be traced back to the Nahuatl (Aztec) word 'mexitli', which was the name of an Aztec god. This shows how the modern term for Mexican identity is directly connected to the indigenous Aztec heritage of the region.

Many Spanish words follow this same pattern of adding '-ano' to a place name to describe people or things from that place. Some simpler examples include 'americano' (American), 'peruano' (Peruvian), and 'cubano' (Cuban). Understanding this pattern can help you recognize and form other nationality words in Spanish.

While not exactly the same, English speakers can recognize the connection to words like 'Mexican' and 'Mexico' in English, which share the same Nahuatl origin. English also borrowed the Spanish pattern for some words, which is why we say 'Mexican' instead of something like 'Mexicish' or 'Mexican'.
