1. Wādi-al-ḥijāra:
Many scholars believe that Guadalajara's name originates from the Arabic phrase "Wādi al-ḥijāra," meaning "valley of stones" or "river of stones." This explanation is supported by the city's location in the Valley of Atemajac, where the presence of canyons, hills, and rocky terrain aligns with the Arabic description. Over time, the phrase was modified and Hispanicized to become Guadalajara.
2. Wādi-al-ḥaŷara:
Another etymological theory suggests that Guadalajara's name comes from the Arabic phrase "Wādi al-ḥaŷara," which translates to "valley of the castle" or "river of the castle." This interpretation links the city's name to its historical role as a strategic point of defense during pre-Hispanic times. The Nahuatl name for the settlement, Tonalá, translates to "place where the sun emerges," further supporting the notion of a fortified place associated with power and protection.
Over the years, the name evolved from the Arabic roots to the Spanish "Guadalajara," influenced by the dominant language of the region and country.
It is worth noting that the above etymologies are widely accepted, but some alternative explanations and interpretations of the city's name have been proposed by historians and researchers, adding depth and complexity to the understanding of Guadalajara's history and cultural origins.
