The Rule
Poder = can/to be able to (ability or permission). Saber = to know (facts, information, how to do something). Conocer = to know (people, places, being familiar with). Saber and conocer CANNOT be interchanged.
Why This Matters
English uses 'know' for both facts and familiarity, but Spanish strictly separates them. Additionally, saber and conocer change meaning in the preterite: 'supe' = I found out, 'conocí' = I met (for the first time).
Examples
• ¿Puedes ayudarme? — "Can you help me?" [Poder: ability/willingness] • Sé hablar francés. — "I know how to speak French." [Saber + infinitive = know how to] • ¿Conoces a María? — "Do you know María?" [Conocer: familiarity with a person (note: personal 'a')] • No sé la respuesta, pero conozco a alguien que sí. — "I don't know the answer, but I know someone who does." [Saber (fact) vs conocer (person)]
Common Mistakes
❌ Conozco la respuesta. ✅ Sé la respuesta. → Facts and information use saber, not conocer. Conocer is for familiarity with people, places, and works. ❌ Sabo nadar. ✅ Sé nadar. → The yo-form of saber is 'sé' (irregular), not 'sabo.' Also, saber + infinitive = to know how to.
Quick Tip
Conocer in the preterite = 'met (for the first time).' Saber in the preterite = 'found out/learned.' These meaning shifts are unique to the preterite.
