In Spanish, the word "you" can be said in several ways depending on the formality, number of people, and region:

• Tú : Informal singular "you," used with friends, family, children, and people the same age or younger. Often used in informal conversations.
• Usted : Formal singular "you," used to show respect to older people, strangers, or in professional settings.
• Vos : Singular "you" used mainly in certain South American regions like Argentina, Uruguay, Paraguay, and parts of Central America, often as a replacement for tú or usted.
• Vosotros/Vosotras : Informal plural "you" mainly used in Spain when addressing multiple people.
• Ustedes : Formal and informal plural "you" used in most Spanish-speaking countries for addressing a group of people.

Each version reflects a different level of formality, number of people being addressed, and sometimes regional usage.
