What is ustedes?

"Ustedes" is a Spanish pronoun used to address a group of people. It is the plural form of "usted," which is a formal way to say "you" in singular when speaking to someone respectfully. "Ustedes" is used in most Spanish-speaking countries to address more than one person, regardless of formality. It's equivalent to "you all" or "you guys" in English. In Spain, however, "vosotros" is often used as the informal plural "you," while "ustedes" remains the formal plural "you." The usage might vary based on region and context.
