Reflexive verbs in Spanish are special verbs where the subject does something to itself. To use them correctly, it's important to understand how they work and follow certain rules.

Key Points for Using Reflexive Verbs

1. What Are Reflexive Verbs?
   Reflexive verbs use reflexive pronouns. These pronouns show that the action is done to oneself. Here are some common ones:

   • me (myself)
   • te (yourself - informal)
   • se (himself, herself, itself, themselves)
   • nos (ourselves)
   • os (yourselves - plural informal)

   For example: "lavarse" means "to wash oneself."

2. Present Tense Conjugation
   To change a reflexive verb to the present tense, do the following:

   • Take off the -se from the end of the verb.
   • Change the rest like a regular verb.
   • Add the correct reflexive pronoun before the verb.

   Here’s how it looks:

   • Yo me lavo (I wash myself)
   • Tú te lavas (You wash yourself - informal)
   • Él/Ella se lava (He/She washes himself/herself)
   • Nosotros nos lavamos (We wash ourselves)
   • Vosotros os laváis (You all wash yourselves - plural informal)
   • Ellos/Ellas se lavan (They wash themselves)

3. Subject Pronouns
   These pronouns tell us who is doing the action:

   • Yo (I)
   • Tú (You - informal)
   • Él/Ella (He/She)
   • Nosotros (We)
   • Vosotros (You all - informal)
   • Ellos/Ellas (They)

4. Adjective Agreement
   In Spanish, adjectives (describing words) must match the nouns they describe. This means they need to agree in gender (masculine or feminine) and number (singular or plural).

   • For example: "las chicas felices" (the happy girls) vs. "el chico feliz" (the happy boy).

5. Making Negatives
   To say something is not happening, put "no" before the verb.

   • Example: "Yo no me lavo" (I do not wash myself).

6. Irregular Verbs
   Some common verbs don’t follow the regular rules. They are called irregular verbs. A few examples include:

   • ser (to be)
   • estar (to be)
   • tener (to have)

   Example: "Yo soy feliz" (I am happy).

7. Using Articles
   Use articles (the words for "the" and "a") correctly:

   • Definite: el (the - masculine), la (the - feminine)
   • Indefinite: un (a - masculine), una (a - feminine)

8. Future Tense
   To talk about future actions, say "ir a + infinitive."

   • Example: "Voy a estudiar español" (I am going to study Spanish).

9. Likes and Dislikes
   To talk about what you like or don’t like, use gustar.

   • Example: "Me gusta la música" (I like music) or "No me gusta el frío" (I do not like the cold).
