What is the formal way to use the plural form for “you” in most of Spain?

Answer 1

In most of Spain, the formal way to use the plural form for "you" is "ustedes." Unlike some Latin American countries where "ustedes" can be used in both formal and informal contexts, in Spain, the more formal plural "you" is often expressed as "vosotros" when addressing a group informally and "ustedes" in formal situations. However, "ustedes" is commonly used in formal settings across different regions.
