The verb "ser" is really important in Spanish. It means "to be."

It's crucial to know how to use it correctly. You’ll often hear it in everyday conversations.

Unlike many other Spanish verbs, "ser" doesn’t follow the usual patterns for changing its form.

Let’s look at how to change "ser" in the present tense and some examples to help you understand.

Here are the present tense forms of "ser":

• Yo soy (I am)
• Tú eres (You are - informal)
• Él/Ella/Usted es (He/She/You are - formal)
• Nosotros/Nosotras somos (We are)
• Vosotros/Vosotras sois (You all are - informal, mostly used in Spain)
• Ellos/Ellas/Ustedes son (They/You all are - formal)

Let’s break this down:

1. Yo soy
   You use this when talking about yourself.

   • Example: Yo soy estudiante. (I am a student.)

2. Tú eres
   Use this for friendly chats with people you know well.

   • Example: Tú eres muy amable. (You are very kind.)

3. Él/Ella/Usted es
   Use "él" for he, "ella" for she, and "usted" for the formal "you." This is for speaking to someone you don't know well.

   • Example with él: Él es médico. (He is a doctor.)
   • Example with ella: Ella es ingeniera. (She is an engineer.)
   • Example with usted: Usted es muy inteligente. (You are very intelligent.)

6. Ellos/Ellas/Ustedes son
   "Ellos" is for a group of boys or a mixed group, while "ellas" is for a group of girls. "Ustedes" means "you all" in a formal way in Latin America and informally in some parts of Spain.
