The imperfect tense can be particularly frustrating because it doesn’t follow predictable patterns like regular verbs.

In this comprehensive guide, we’ll explore proven techniques to help you quickly memorize 15 common irregular verbs in the imperfect tense.

Lesson Timing

This lesson is designed to take approximately 25-30 minutes to complete—significantly less than the typical 2-hour grammar session many language courses devote to irregular verb forms. By focusing on high-frequency verbs and using memory-optimized techniques, you’ll gain practical mastery in about one-fourth the usual time. Set aside a distraction-free half hour, grab a notebook, and let’s dive in!

Step 1: Understand What Makes Imperfect Irregular Verbs Challenging

Before memorizing forms, it’s crucial to understand why some verbs are irregular in the imperfect past tense Spanish and other languages. Irregular verbs don’t follow the standard conjugation patterns because they’ve retained older forms from earlier versions of the language. This historical quirk is why they often seem random, but there are actually patterns within the irregularity.

Step 2: Group Verbs by Pattern Similarities

Instead of memorizing each verb individually, group them by similar patterns:

1. Stem-changing verbs (e → ie): querer → quería
2. Fully irregular forms: ser → era, ir → iba
3. Special ending verbs: ver → veía

This pattern recognition reduces 15 verbs to just 3-4 patterns, making memorization much more manageable.

Step 3: Practice With Flashcard Rotation

Create flashcards with the infinitive on one side and the conjugated imperfect form Spanish on the other. Use the “Leitner System” of spaced repetition:

• Cards you know well go into Box 1 (review weekly)
• Cards you struggle with go into Box 2 (review daily)
• New cards go into Box 3 (review twice daily)

This evidence-based approach ensures you spend more time on difficult verbs and less on those you’ve mastered.

2. Applying regular endings: Don’t add regular endings to irregular stems (×hacaba instead of ✓hacía).
3. Forgetting accent marks: Many irregular imperfect forms require accent marks that change pronunciation and meaning.
4. Over-regularizing: Not all verbs that seem irregular are truly irregular in the imperfect tense.

Practice & Review Tips

1. Create sentence templates with blanks for verb forms
2. Record yourself using these verbs and listen back
3. Use color-coding to highlight pattern similarities
4. Practice with a language exchange partner for immediate feedback
