Learning how to use irregular verbs in the past tense can be a little challenging.

Let's look at two important verbs in Spanish: "ir" (which means "to go") and "ser" (which means "to be").

What’s interesting is that these two verbs look the same when we use them in the past tense!

Conjugating "ir" and "ser" in the Past Tense

Here’s how you change "ir" and "ser" for different subjects:

| Subject Pronoun | "Ir" (To Go) | "Ser" (To Be) | |------------------|---------------|----------------| | Yo | fui | fui | | Tú | fuiste | fuiste | | Él/Ella/Usted | fue | fue | | Nosotros/as | fuimos | fuimos | | Vosotros/as | fuisteis | fuisteis | | Ellos/Ellas/Ustedes | fueron | fueron |

Important Points to Remember

1. What is the Past Tense?

   • The past tense is used for actions that already happened.
   • It’s really important to know how to use "ir" and "ser" because we use them a lot!

2. How to Use Them:

   • Example with "ir": Ayer, fui al supermercado. (This means "Yesterday, I went to the supermarket.")
   • Example with "ser": La reunión fue a las tres. (This means "The meeting was at three.")

3. What Makes Them Different?

   • "Ir" and "ser" are not like regular verbs.
   • Regular verbs follow set patterns, but these two verbs do not. For example, verbs like "hablar" (to speak) and "comer" (to eat) change in clear ways in the past.

Practice Time!

Try filling in the blanks with "ir" and "ser" in these sentences:

1. (Yo) _______ a la playa el sábado. (I went to the beach on Saturday.)
2. (Nosotros) _______ estudiantes en la universidad. (We were students at the university.)

Answers:

1. fui
2. fuimos
