Imperfect Tense Basics for Beginners

Master the imperfect tense to talk about past habits, descriptions, and ongoing actions in the past. It's easier than the preterite with very few irregulars!

What Is the Imperfect Tense?

The imperfect tense describes:

• Past habits: "I used to play"
• Ongoing past actions: "I was playing"
• Descriptions in the past: "It was sunny"
• Background information: "While I was studying..."
• Age in the past: "I was 10 years old"

English equivalents: "used to," "was/were -ing," "would" (habitual)

Imperfect vs. Preterite: The Key Difference

Preterite: Completed Actions

• One-time events: Comí pizza ayer. (I ate pizza yesterday.)
• Specific completed actions: Fui a la escuela. (I went to school.)

Imperfect: Ongoing/Habitual/Descriptive

• Habits: Comía pizza todos los días. (I used to eat pizza every day.)
• Ongoing: Mientras comía... (While I was eating...)
• Descriptions: Era un día bonito. (It was a beautiful day.)

Think of it this way:

• Preterite = What happened (completed)
• Imperfect = What was happening, used to happen, or how things were

How to Form the Imperfect

Regular Verbs: Super Easy!

Unlike other tenses, imperfect has only 2 sets of endings (not 3)!

-AR Verbs: Add -ABA endings

Example: HABLAR

Note: Only NOSOTROS has an accent mark!

-ER and -IR Verbs: Same Endings!

Good news: -ER and -IR verbs share the same imperfect endings!

Example: COMER (to eat)

Example: VIVIR (to live)

Note: ALL forms have accent marks for -ER/-IR verbs!

Irregular Verbs: Only 3!

Great news: The imperfect has ONLY 3 irregular verbs!

1. SER (to be)

Examples:

• Yo era muy tímido. (I was very shy.)
• Éramos amigos. (We were friends.)

2. IR (to go)

Examples:

• Yo iba a la escuela todos los días. (I used to go to school every day.)
• Íbamos al parque. (We used to go to the park.)

3. VER (to see)

Examples:

• Veía mucha televisión. (I used to watch a lot of TV.)
• Veíamos películas juntos. (We used to watch movies together.)

That's it! Only 3 irregular verbs to memorize!

Uses of the Imperfect

1. Past Habits (Used to...)

Actions that happened repeatedly in the past:

Trigger words: siempre (always), todos los días (every day), generalmente (usually), a menudo (often), cuando era niño/a (when I was a child)

2. Ongoing Past Actions (Was/Were -ing)

Actions in progress in the past:

3. Descriptions in the Past

Describing how things were:

4. Age in the Past

Always use imperfect for age:

5. Time in the Past

Common Imperfect Time Expressions

Frequency Expressions

"While" Expressions

Imperfect vs. Preterite in the Same Sentence

Often, the imperfect sets the scene (background) and the preterite tells what happened (action):

Pattern: IMPERFECT (background/ongoing) + PRETERITE (what happened)

Common Mistakes to Avoid

❌ Mistake 1: Using preterite for habits instead of imperfect

• Wrong: "Jugué fútbol todos los días" (sounds like one specific time)
• Right: "Jugaba fútbol todos los días" (I used to play soccer every day)

❌ Mistake 2: Forgetting accent marks

• Wrong: "Yo comia" (all -ER/-IR forms need accents)
• Right: "Yo comía"

❌ Mistake 3: Using imperfect for completed one-time actions

• Wrong: "Ayer comía pizza" (sounds ongoing)
• Right: "Ayer comí pizza" (I ate pizza yesterday - completed)
• Imperfect: "Comía pizza todos los días" (I used to eat - habit)

❌ Mistake 4: Confusing SER irregular forms

• Wrong: "Yo sería" (that's conditional!)
• Right: "Yo era" (I was)

❌ Mistake 5: Using imperfect incorrectly with specific completed times

• With "ayer" (yesterday), "anoche" (last night): usually preterite
• With "siempre" (always), "todos los días" (every day): usually imperfect
