Confusing 'comprobar' and 'chequear'

In the present tense, the 'o' changes to 'ue' when the stress falls on the root word (e.g., 'yo compruebo'). This change skips the 'nosotros' and 'vosotros' forms.

Stem Change 'O' to 'UE'

Use 'comprobar' when you are officially verifying a fact or testing a theory. Use 'revisar' for checking homework or looking over a list.

Formal vs. Informal Check

Very common when talking about verifying facts, checking documents, or confirming information.

When 'comprobar' means 'to prove' or 'to confirm a fact,' it is usually followed by 'que' and the verb in the normal indicative (non-special) form: 'Comprobamos que está aquí.' (We confirmed that he is here.)

Followed by 'que'

If you are trying to convince someone of the truth of a statement, use 'comprobar' in this sense. If you are just making sure your keys are in your pocket, use 'revisar' or 'check' (meaning 1).

Proof vs. Check

Common in academic or technical language when referring to proving a result or hypothesis.

Learn the Spanish verb 'comprobar,' meaning both 'to check/verify' and 'to prove/demonstrate.' Includes full stem-changing conjugation tables (o > ue) and usage examples for all levels.

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.
