1. Definition of the Imperfect Tense

The imperfect tense (pretérito imperfecto or copretérito) in Spanish is a past tense used to describe actions, conditions, or events that were ongoing, habitual, or incomplete in the past. Unlike the preterite tense, which focuses on completed actions, the imperfect tense emphasizes the duration, frequency, or state of being in the past. It provides background information, sets the scene, and describes what was happening rather than what happened.

The imperfect tense is often used to describe:

• Descriptions: Describing people, places, or things in the past.
• Habitual Actions: Actions that occurred repeatedly in the past.
• Ongoing Actions: Actions that were in progress at a specific time in the past.
• Age and Time: Stating age or telling time in the past.
• Mental and Emotional States: Describing feelings, thoughts, and beliefs in the past.
• Simultaneous Actions: Actions that were happening at the same time in the past.

2. Structural Breakdown

Forming the imperfect tense involves conjugating verbs according to their endings (-ar, -er, or -ir). There are relatively few irregular verbs in the imperfect tense, making it easier to learn compared to other tenses.

2.1 Regular Verb Conjugations

To conjugate regular verbs in the imperfect tense, you remove the infinitive ending (-ar, -er, or -ir) and add the appropriate imperfect endings. Here’s a breakdown of the endings for each type of verb:

-AR Verbs:

• Yo: -aba
• Tú: -abas
• Él/Ella/Usted: -aba
• Nosotros/Nosotras: -ábamos
• Vosotros/Vosotras: -abais
• Ellos/Ellas/Ustedes: -aban

-ER and -IR Verbs:

• Yo: -ía
• Tú: -ías
• Él/Ella/Usted: -ía
• Nosotros/Nosotras: -íamos
• Vosotros/Vosotras: -íais
• Ellos/Ellas/Ustedes: -ían

The following table illustrates the conjugation of regular verbs in the imperfect tense:

Pronoun	Hablar (to speak)	Comer (to eat)	Vivir (to live)
Yo	Hablaba	Comía	Vivía
Tú	Hablabas	Comías	Vivías
Él/Ella/Usted	Hablaba	Comía	Vivía
Nosotros/Nosotras	Hablábamos	Comíamos	Vivíamos
Vosotros/Vosotras	Hablabais	Comíais	Vivíais
Ellos/Ellas/Ustedes	Hablaban	Comían	Vivían

2.2 Irregular Verb Conjugations

Fortunately, there are only three irregular verbs in the imperfect tense: ser (to be), ir (to go), and ver (to see). Their conjugations are as follows:

Ser (to be):

• Yo: Era
• Tú: Eras
• Él/Ella/Usted: Era
• Nosotros/Nosotras: Éramos
• Vosotros/Vosotras: Erais
• Ellos/Ellas/Ustedes: Eran

Ir (to go):

• Yo: Iba

5. Usage Rules

Understanding the rules governing the use of the imperfect tense is essential for accurate and fluent communication.

5.1 Contrasting with the Preterite Tense

The key to mastering the imperfect tense lies in understanding its contrast with the preterite tense. The preterite describes completed actions, while the imperfect describes ongoing, habitual, or descriptive actions. Consider these examples:

• Preterite: Ayer fui al cine. (Yesterday I went to the movies.) – Completed action.
• Imperfect: Cuando era niño, iba al cine todos los sábados. (When I was a child, I used to go to the movies every Saturday.) – Habitual action.

Another example:

• Preterite: Ella cantó una canción. (She sang a song.) – Completed action.
• Imperfect: Ella cantaba mientras yo tocaba la guitarra. (She was singing while I was playing the guitar.) – Ongoing action.

The following table summarizes the key differences between the preterite and imperfect tenses:

Tense	Use	Example
Preterite	Completed actions, specific events	Comí una manzana. (I ate an apple.)
Imperfect	Ongoing actions, habitual actions, descriptions	Comía manzanas todos los días. (I used to eat apples every day.)

5.2 Signal Words and Phrases

Certain words and phrases often indicate the use of the imperfect tense. These signal words provide clues about the context and help determine the appropriate tense.

Common signal words include:

• Siempre (always)
• Generalmente (generally)
• Normalmente (normally)
• A menudo (often)
• Muchas veces (many times)
• Cada día/semana/mes/año (every day/week/month/year)
• Todos los días/seman

  as/meses/años (every day/week/month/year)

• Mientras (while)
• Cuando era niño/joven (when I was a child/young)
• Antes (before)
• En aquella época (at that time)

For example:

• Siempre iba al parque después de la escuela. (I always used to go to the park after school.)
• Mientras estudiaba, escuchaba música. (While I was studying, I was listening to music.)

6. Common Mistakes

Even advanced learners sometimes make mistakes with the imperfect tense. Here are some common errors and how to avoid them:

• Confusing with the Preterite: Using the preterite when the imperfect is needed, or vice versa. Remember to distinguish between completed actions (preterite) and ongoing/habitual actions (imperfect).
• Incorrect Conjugations: Making errors in verb conjugations, especially with irregular verbs. Practice the conjugations of ser, ir, and ver.
• Forgetting Signal Words: Overlooking signal words that indicate the use of the imperfect tense. Pay attention to words like siempre, mientras, and cada día.
• Using the Imperfect for Specific Events: Using the imperfect tense to describe a single, completed event. The preterite tense is more appropriate for such instances.
• Misunderstanding Descriptions: Failing to use the imperfect tense for descriptions of people, places, or things in the past. Remember that the imperfect sets the scene and provides context.

Example of a common mistake:

• Ayer yo fui a la tienda a menudo. Ayer yo iba a la tienda a menudo. (Yesterday I went to the store often.) – Incorrect use of preterite with “a menudo”.

8. Advanced Topics

Beyond its basic uses, the imperfect tense has some advanced applications that can add subtlety and nuance to your Spanish.

8.1 Imperfect for Polite Requests

The imperfect tense can be used to make polite requests or suggestions, softening the tone and making the request less direct. This is particularly common with verbs like querer (to want) and poder (to be able to).

Examples:

• Quería pedirte un favor. (I wanted to ask you a favor.) – More polite than “Quiero pedirte un favor.”
• ¿Podías ayudarme con esto? (Could you help me with this?) – More polite than “¿Puedes ayudarme con esto?”

8.2 Imperfect in Hypothetical Situations

The imperfect subjunctive, often paired with the conditional tense, is used to describe hypothetical situations or express wishes. This construction adds a layer of complexity and allows for more nuanced expression.

Examples:

• Si tuviera dinero, viajaría por el mundo. (If I had money, I would travel the world.)
• Me gustaría que estuvieras aquí. (I would like you to be here.)
