When you want to make sentences that say “no” in Spanish, especially with tricky verbs, it’s very important to know how to use them. Let’s look at some key points that will help you understand this better.

1. Regular Verbs in Present Tense
Regular verbs in Spanish fall into three groups based on their endings: -ar, -er, and -ir. Here’s how to use them:

• -ar verbs (like “hablar” which means to speak)

  • Yo hablo (I speak)
  • Tú hablas (You speak)

• -er verbs (like “comer” which means to eat)

  • Yo como (I eat)
  • Tú comes (You eat)

• -ir verbs (like “vivir” which means to live)

  • Yo vivo (I live)
  • Tú vives (You live)

2. Irregular Verbs in Present Tense
Some verbs do not follow the regular rules. Here are some important irregular verbs:

• Hacer (to do/make)

  • Yo hago (I do/make)
  • Tú haces (You do/make)

• Ir (to go)

  • Yo voy (I go)
  • Tú vas (You go)

• Ser (to be)

  • Yo soy (I am)
  • Tú eres (You are)

• Tener (to have)

  • Yo tengo (I have)
  • Tú tienes (You have)

3. Using "ser" vs. "estar"
It’s important to know when to use "ser" and "estar."

• Ser is for things that don’t change, like traits.
• Estar is for things that can change, like feelings.

Examples:

• Ser: Ella es alta. (She is tall.)
• Estar: Ella está cansada. (She is tired.)

4. Making Negative Sentences
To make a negative sentence in Spanish, just put "no" in front of the verb.

Examples:

• Yo no hablo español. (I do not speak Spanish.)
• Tú no haces la tarea. (You do not do the homework.)
• Ella no está aquí. (She is not here.)

5. Asking Questions
To ask a question, you can switch the subject and the verb around.

Example:

• ¿No vas al cine? (Aren't you going to the movies?)

6. Matching Adjectives
Adjectives must match the nouns they describe in gender (like male or female) and number (like singular or plural).

Examples:

• El coche rojo (The red car - masculine singular)
• Las casas rojas (The red houses - feminine plural)

By practicing these rules and examples, you will get better at making correct negative sentences with irregular verbs in Spanish!
