In Spanish, regular verbs fall into three groups based on how they end: -ar, -er, and -ir. This lesson will focus on -ar and -ir verbs in the present tense.

1. Changing -ar Verbs

To change -ar verbs, just follow these simple steps:

1. Remove the -ar ending.
2. Add the new endings depending on who you are talking about:

• yo (I): -o (hablo)
• tú (you): -as (hablas)
• él/ella/usted (he/she/you formal): -a (habla)
• nosotros (we): -amos (hablamos)
• vosotros (you all, informal in Spain): -áis (habláis)
• ellos/ellas/ustedes (they/you all formal): -an (hablan)

For example, the verb "hablar" means "to speak."

2. Changing -ir Verbs

To change -ir verbs, here’s what you do:

1. Remove the -ir ending.
2. Add these endings based on who you’re talking about:

• yo (I): -o (vivo)
• tú (you): -es (vives)
• él/ella/usted (he/she/you formal): -e (vive)
• nosotros (we): -imos (vivimos)
• vosotros (you all, informal in Spain): -ís (vivís)
• ellos/ellas/ustedes (they/you all formal): -en (viven)

For example, the verb "vivir" means "to live."

By learning these patterns, you will find it easier to create sentences and expand your Spanish vocabulary!
