The Spanish word 'chilango', which refers to a person from Mexico City, has interesting roots in the Maya language. It comes from the Maya word 'xilaan', which meant 'disheveled hair' or 'ragged clothes'. This first evolved into the now-archaic Spanish term 'xilango' before becoming the modern 'chilango'. The shift from 'x' to 'ch' is a common phonetic change in Spanish words borrowed from indigenous languages of Mexico.

While the original Maya term had to do with appearance or clothing, the meaning shifted to become a demonym specifically for residents of Mexico City. Today, 'chilango' is widely used, though it can sometimes carry slightly pejorative connotations depending on context and who is using it.

Since 'chilango' comes from Maya rather than Latin or Greek roots, there aren't many common Spanish words that share its etymology. This is typical of words that entered Spanish from indigenous American languages.

There are no common English words related to 'chilango', as it comes from Maya rather than the Indo-European roots that English and Spanish often share. English speakers simply use phrases like 'Mexico City resident' or borrow the Spanish word 'chilango' directly when needed.
