The spelling of the surname "Solorzano" can be a bit tricky for English speakers unfamiliar with Spanish pronunciation. The correct pronunciation is [so.loɾ.'θa.no], with stress on the second to last syllable. The "s" at the beginning is pronounced as in "sun" and the "o" is short. The "rr" is a rolled or tapped "r" sound, and the "z" is pronounced like "th" in "thin." The "a" and "no" are both pronounced separately and clearly.
The name "Solorzano" is of Spanish origin. It is derived from the words "solo" meaning "alone" or "only", and "zarza" which means "blackberry bush" in Spanish. Therefore, "Solorzano" can be interpreted as "the place where blackberry bushes grow alone" or "the lonely blackberry bush". It is a fairly common surname in Spanish-speaking countries, particularly in Spain, Mexico, and some parts of Latin America.
