Unlike English, where verbs barely change (I work, you work, he works), Czech verbs carry rich information about who is performing the action. Each person (I, you, he/she, we, you all, they) has a unique verb ending.
This means pronouns are often optional in Czech. When you say “Dělám” (I do), the -ám ending already tells the listener it’s “I”—no pronoun needed. This frees Czech for flexible word order that English lost centuries ago.
Pattern Recognition is Key
Czech verbs group into 5 main classes based on their infinitive ending. Once you recognize the class, you know exactly how to conjugate the verb. This is far more efficient than memorizing each verb individually.

How to Use This Module
1. Learn the Patterns
Click on each verb class to see detailed explanations, stem formation rules, and example verbs with full conjugation tables.
2. Practice with Filters
Use the practice mode to drill specific combinations: certain verb classes, specific persons (já, ty, oni...), tenses, or aspects.
3. Master Aspect
Czech verbs come in pairs: imperfective (ongoing/repeated) and perfective (completed/single). Learn to choose the right one.
Key insight: Don’t memorize individual verbs—memorize the patterns. Once you know that -at verbs use -ám, -áš, -á, -áme, -áte, -ají, you can conjugate hundreds of verbs correctly. The same applies to each class.
