Arechiga
A Spanish-language surname likely tied to a Basque place-name tradition, with the exact origin uncertain.
The #9,794 most common surname in the United States (2010 Census) — about 1 in every 93,389 Americans shares it.
Etymology
Arechiga is likely a Hispanicized surname of Basque origin, formed from a place-name or local topographic name. The Basque-looking element aritz/aretx- often refers to an oak, and many surnames of this type began as names for a farmstead, village, or landscape feature. The ending is not perfectly transparent in modern form, so the exact original meaning is uncertain.
History
The surname is most strongly associated today with Mexico and Mexican-American families, reflecting the long spread of Spanish surnames in the Americas. Like many Basque-origin surnames in Hispanic usage, it may have entered family naming through migration from the Basque Country into wider Spanish-speaking communities. Modern spellings can vary because older place-name forms were adapted to Spanish orthography over time.
