Negation words like "no" and "nunca" are super important in Spanish. Let’s break down how to use them:

1. Basic Negation

• No: You put this word before the verb.
  Example: No como (I do not eat).

• Nunca: This word means "never." You use it in a similar way.
  Example: Nunca como (I never eat).

2. Present Tense Verb Conjugation

• For regular verbs, here’s how it works:
  • -ar: hablar → No hablo (I do not speak).
  • -er: comer → No como (I do not eat).
  • -ir: vivir → No vivo (I do not live).

3. Irregular Verbs

Here are some that don’t follow the regular rules:

• Ser: No soy (I am not).
• Estar: No estoy (I am not).
• Ir: No voy (I do not go).

4. How to Make Sentences

Follow this order: subject + no + verb + object.
Example: Yo no estudio matemáticas (I do not study math).

5. Articles and Plural Nouns

• Use "el" or "la" for specific things and "un" or "una" for general ones.
• For plural you use: los/las or unos/unas.
  Example: No tengo libros (I do not have books).

6. Questions and Adjectives

• To make a question negative, you can say: ¿No tienes amigos? (Do you not have friends?).
• Adjectives need to match in gender and number.
  Example: no buenos amigos (not good friends).

7. Negation with Reflexive Verbs

Example: No me despierto temprano (I do not wake up early).

Using "no" and "nunca" correctly will help you make clearer sentences in Spanish. Keep practicing these examples to improve!
