Frequently Asked Questions
Can I use 'saber' + infinitive and 'poder' + infinitive for the same skill?
Yes, but they mean different things. 'Sé nadar' means 'I know how to swim' (I have the skill). 'Puedo nadar' means 'I can swim' (I am able to swim right now). You might know how to swim, but you can't swim today because the pool is closed ('Sé nadar, pero hoy no puedo').
Why does 'saber' sometimes mean 'to taste like'?
It's an idiomatic use of the verb. Think of it as the food 'knowing of' a certain flavor. It's a specific use you just have to memorize, but it's only used for food and drink, so the context makes it clear.
Is the 'saber'/'poder' distinction similar to 'saber'/'conocer'?
They are related but different. 'Saber' vs. 'poder' is about knowing vs. being able to. 'Saber' vs. 'conocer' is about two different types of knowing: knowing facts (saber) vs. being familiar with people, places, or things (conocer).
