How to Conjugate Saber in Spanish — All Tenses with Examples
Saber — “to know” — is one of those verbs that catches learners off guard. In English, “to know” does everything: you know a person, you know a fact, you know how to cook. In Spanish, that work is split between saber and conocer, and using the wrong one is a tell-tale error.
Saber also has an irregular yo form in the present (sé), a completely irregular preterite, and an irregular future. Worth drilling carefully. At VerbPal, this is exactly the kind of verb we want learners to produce actively, not just recognize. Seeing sé on a chart is easy; typing it correctly under pressure is what makes it stick.
Saber vs Conocer — Know This First
Before the conjugation tables, this distinction matters:
*Sabe cocinar.* (She knows how to cook.)
*¿Sabes dónde está?* (Do you know where it is?)
*No sé qué decir.* (I don't know what to say.)
*¿Conoces Madrid?* (Do you know Madrid?)
*Nos conocemos bien.* (We know each other well.)
*No lo conozco.* (I don't know him.)
A practical shortcut: if you’re talking about information, a fact, an answer, or how to do something, you usually want saber. If you’re talking about familiarity with a person, place, or thing, you usually want conocer. In VerbPal, we recommend drilling these as contrast pairs so your brain stops translating from English and starts noticing the Spanish pattern directly.
Pro Tip: Write two short lists: “things I know” with saber and “people/places I know” with conocer. Then say them out loud and type them from memory.
Present Tense — Presente
The yo form sé is irregular (and noticeably short). All other forms are regular:
| Person | Form | Example |
|---|---|---|
| yo | sé | No sé la respuesta. (I don’t know the answer.) |
| tú | sabes | ¿Sabes hablar chino? (Do you know how to speak Chinese?) |
| él/ella | sabe | Sabe mucho de historia. (He knows a lot about history.) |
| nosotros | sabemos | No sabemos qué hacer. (We don’t know what to do.) |
| vosotros | sabéis | ¿Sabéis la dirección? (Do you all know the address?) |
| ellos/ellas | saben | Saben la verdad. (They know the truth.) |
The main trap here is overthinking the irregularity. Only yo changes: sé. The rest behave like a regular -er verb. That makes this a good tense to practice with fast production drills: one irregular anchor, five predictable forms. On VerbPal, our custom drills are useful here because they force you to produce sé repeatedly in contrast with sabes, sabe, and sabemos until the odd form stops feeling odd.
Pro Tip: Memorize the present as one chunk: sé, sabes, sabe, sabemos, sabéis, saben. Say it three times without looking, then use each form in a sentence.
Preterite Tense — Pretérito Indefinido
Completely irregular — stem sup- with strong preterite endings:
| Person | Form | Example |
|---|---|---|
| yo | supe | Supe la noticia ayer. (I found out / learned the news yesterday.) |
| tú | supiste | ¿Cómo lo supiste? (How did you find out?) |
| él/ella | supo | Nunca lo supo. (He never found out.) |
| nosotros | supimos | Lo supimos demasiado tarde. (We found out too late.) |
| vosotros | supisteis | ¿Cuándo lo supisteis? (When did you all find out?) |
| ellos/ellas | supieron | Supieron la verdad. (They found out the truth.) |
Important nuance: saber in the preterite often means “to find out” or “to learn” — the moment of knowing, rather than ongoing knowledge.
This is one of the highest-value meaning shifts to learn early. Sabía = “I knew.” Supe = “I found out.” If you miss that contrast, you can conjugate correctly and still say the wrong thing. That is why we treat tense and meaning together in VerbPal rather than as separate memorization tasks.
Pro Tip: Pair the two ideas directly: sabía = knew, supe = found out. Then create two mini-timelines with your own examples: one ongoing, one momentary.
Imperfect Tense — Pretérito Imperfecto
Regular imperfect forms:
| Person | Form | Example |
|---|---|---|
| yo | sabía | Sabía que tenía razón. (I knew I was right.) |
| tú | sabías | ¿Sabías que era mentira? (Did you know it was a lie?) |
| él/ella | sabía | Sabía exactamente qué decir. (He knew exactly what to say.) |
| nosotros | sabíamos | No sabíamos nada. (We didn’t know anything.) |
| vosotros | sabíais | ¿Sabíais la contraseña? (Did you all know the password?) |
| ellos/ellas | sabían | Sabían lo que hacían. (They knew what they were doing.) |
The imperfect is the “background knowledge” tense. Use it for what someone knew, used to know, or was aware of over a period of time. Compared with the preterite, this one is less about a discovery and more about a state.
Pro Tip: Test yourself with this question: was it a state of knowledge or a moment of discovery? If it was a state, start with the imperfect.
Future Tense — Futuro Simple
Uses the irregular stem sabr-:
| Person | Form | Example |
|---|---|---|
| yo | sabré | Sabré la respuesta mañana. (I’ll know the answer tomorrow.) |
| tú | sabrás | Pronto lo sabrás. (You’ll know soon.) |
| él/ella | sabrá | Sabrá la verdad. (He’ll find out the truth.) |
| nosotros | sabremos | Sabremos los resultados el lunes. (We’ll know the results on Monday.) |
| vosotros | sabréis | ¿Lo sabréis para entonces? (Will you all know by then?) |
| ellos/ellas | sabrán | Nunca lo sabrán. (They’ll never know.) |
The key here is the stem sabr-, not saber-.
Many advanced learners improve faster once they stop memorizing future forms one by one and start grouping irregular stems: tendr-, saldr-, podr-, sabr-. Our interactive conjugation charts at VerbPal make these stem families easier to spot, which matters because irregular futures are much more manageable when you learn the pattern, not just the isolated verb.
Pro Tip: Make a short irregular-future list with saber plus three other common verbs. Learn the stems together, not separately.
Conditional — Condicional Simple
Same sabr- stem:
| Person | Form |
|---|---|
| yo | sabría |
| tú | sabrías |
| él/ella | sabría |
| nosotros | sabríamos |
| vosotros | sabríais |
| ellos/ellas | sabrían |
¿Sabrías decirme cómo llegar? (Would you be able to tell me how to get there?)
The conditional often appears in polite requests and hypothetical situations. Since it shares the sabr- stem with the future, it makes sense to study those two tenses together.
Pro Tip: Learn the pair as a set: sabré / sabría, sabrás / sabrías, and so on. Shared stems reduce memorization load.
Present Subjunctive — Presente de Subjuntivo
| Person | Form |
|---|---|
| yo | sepa |
| tú | sepas |
| él/ella | sepa |
| nosotros | sepamos |
| vosotros | sepáis |
| ellos/ellas | sepan |
No quiero que lo sepa nadie. (I don’t want anyone to know.)
Es importante que sepamos la verdad. (It’s important that we know the truth.)
The subjunctive forms come from the first-person present: sé → drop the -o pattern doesn’t apply neatly here, so it’s best to memorize the subjunctive set directly: sepa, sepas, sepa, sepamos, sepáis, sepan. If you’re serious about fluency, this is where passive study stops working. VerbPal covers the subjunctive alongside core tenses, irregulars, and reflexives because real Spanish does not wait until “later” to use them.
Pro Tip: Start with trigger phrases you actually use: Es importante que…, No creo que…, Quiero que… Then plug in sepa forms.
Imperative — Imperativo
| Form | Command |
|---|---|
| tú (affirmative) | sabe |
| tú (negative) | no sepas |
| usted | sepa |
| nosotros | sepamos |
| vosotros | sabed |
| ustedes | sepan |
Sepa que tiene todo nuestro apoyo. (Know that you have our full support.)
Imperatives with saber are less common in everyday beginner speech, but you will see them in formal or fixed expressions. The useful takeaway is that command forms often connect back to forms you already know, especially the subjunctive-based negatives and formal commands.
Pro Tip: Focus first on recognition, then learn the most useful forms: sepa, sepan, and no sepas.
Non-Finite Forms
| Form | Spanish |
|---|---|
| Infinitive | saber |
| Gerund | sabiendo |
| Past participle | sabido |
These matter because they show up inside larger structures: sin saber (without knowing), está sabiendo is rare, and sabido appears more often as an adjective in some contexts than in everyday compound tenses.
Pro Tip: Learn each non-finite form inside a phrase, not alone: sin saber, habiendo sabido, es bien sabido.
Essential Saber Phrases
- No sé. (I don’t know.)
- ¿Sabes qué? (You know what? / Guess what?)
- Saber de — to know about: Sabe mucho de música. (He knows a lot about music.)
- Saber a — to taste like: Sabe a chocolate. (It tastes like chocolate.)
- ¡A saber! (Who knows! / Goodness knows!)
- Que yo sepa (As far as I know)
These chunks are worth memorizing as complete units. They come up often, and they help you move from isolated conjugation knowledge to actual use. In VerbPal, phrase-level practice is where learners usually start feeling the payoff of verb study: the form is no longer abstract because it lives inside something you can actually say.
Pro Tip: Pick three phrases from this list and use each one in a message, journal entry, or short spoken response today.

Saber is deceptively tricky — the single-letter yo form (sé), the completely irregular preterite, and the saber vs conocer distinction all need conscious attention. But once you have them, you’re using one of the most important verbs in the language with genuine precision.
