Why learn the whole table?

A verb is not one word — it is dozens. Spanish hablar becomes hablo, hablas, habla, hablamos, habláis, hablan in the present alone, and then the past, the future, the subjunctive and the imperative each add their own set. The regular patterns are learnable in an afternoon. The trouble is the irregular verbs — and they are the verbs you use most: to be, to have, to go, to do, to say.

That is why VerbFlow shows the whole table, not just the form you asked for. Seeing soy, eres, es next to fui, fuiste, fue is what makes the pattern stick — and seeing the irregular forms marked as irregular is what stops you applying a regular rule where it does not belong. Every table comes from a rule-based engine plus curated irregular tables, checked against standard references, with IPA pronunciation and translation for every form.

The same honesty applies to the rest of the site. A conjugation is a claim about a language, and a wrong one is worse than no page at all — so every page says where its forms come from, and every page asks you to report a mistake if you find one. Read how we work in our Editorial Policy, and start with the Spanish verb conjugator or the conjugation quiz.


Frequently asked questions

How do you conjugate ser in Spanish?

Ser is irregular: yo soy, tú eres, él/ella es, nosotros somos, vosotros sois, ellos son. Its past is fui, fuiste, fue, fuimos, fuisteis, fueron — the same forms as ir (to go), so context tells them apart. The full table, with every tense, is in the guide to conjugating ser in Spanish.

What is the difference between ser and estar?

Both mean 'to be'. Ser is for what something is — identity, origin, traits, time, material. Estar is for how or where something is — location, condition, mood, temporary states. Soy estudiante (I am a student) but estoy cansado (I am tired). The rule has exceptions, and the ser vs estar guide covers them.

How do you conjugate être in French?

Être is irregular: je suis, tu es, il/elle est, nous sommes, vous êtes, ils/elles sont. Its past participle is été, and it takes être itself as its auxiliary in compound tenses: je suis allé, elle est venue. The full table is in the guide to conjugating être in French.

How do you conjugate sein in German?

Sein is irregular: ich bin, du bist, er/sie/es ist, wir sind, ihr seid, sie sind. Its past is ich war, and its perfect uses sein itself: ich bin gewesen. The full table, with Konjunktiv forms, is in the guide to conjugating sein in German.

Are the conjugations on VerbFlow accurate?

Yes — as accurate as we can make them. Every table comes from a rule-based conjugation engine plus curated irregular-verb tables, checked against standard grammar references. But language is full of exceptions, so if a form looks wrong, verify it in a dictionary or grammar and tell us on the Contact page. A wrong conjugation is worse than no page at all.
