Test your knowledge with interactive exercises

Verb conjugation is the backbone of Spanish communication. Every sentence you speak or write requires at least one conjugated verb, and getting it right determines whether you sound fluent or confused.

The good news: Spanish has clear patterns. Regular -ar, -er, and -ir verbs follow predictable rules, and the 20 most common irregular verbs cover the vast majority of everyday conversation. Master those, and you''re already ahead of most learners.

Past, present, future, hypothetical — conjugations let you place actions exactly when they happened or might happen.

Wrong conjugations can change who did what. ''Hablé'' (I spoke) vs ''habló'' (he spoke) — one accent mark, completely different meaning.

DELE, AP Spanish, and university placement tests all heavily test conjugation accuracy. It''s the most testable skill in Spanish.

When conjugation becomes automatic, you stop translating in your head and start thinking directly in Spanish. That''s true fluency.

Spanish has 14 major verb tenses across 3 moods (indicative, subjunctive, imperative), but just 3 tenses — present, preterite, and imperfect — account for over 80% of verbs used in everyday speech. Focus there first.
