Confusing informal vs. formal 'you'

Forgetting the Stem Change in Other Forms

'Mentiste' is the simple past (called the preterite) form for 'tú' (you). Use it when the lying happened once and finished completely in the past.

When to use 'mentiste'

The ending, -iste, is the standard way to conjugate the 'tú' form in the simple past for almost all verbs ending in -er and -ir, even irregular ones like 'mentir'.

The 'Tú' Past Ending

Using 'mentiste' is very direct. If you want to soften the accusation, you might say 'Creo que no estás diciendo la verdad' (I think you aren't telling the truth).

Directness

Extremely common way to tell someone, informally, that they told a lie in the past.

'Mentiste' means 'you lied' (informal, past tense). Learn its conjugation, usage tips, and common mistakes related to the irregular verb 'mentir.'

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.
