23. The Verb "Saber"

Source: video

Saber means "to know" — but specifically, knowing factual information or knowing how to do something. The video frames it as the cognitive cousin of ser: just as ser describes factual identity, saber describes factual knowledge.

Key Rules

Use saber for factual information (dates, times, facts).
Use saber for knowing how to do something (skills, abilities).
Conjugates regularly except in yo: sé (with an accent to distinguish from se, the reflexive/IOP).
Spanish drops the word cómo ("how") in "I know how to ___": Yo sé hablar español (not sé cómo hablar).

Conjugation / Pattern Tables

Examples

Spanish	English

Notes & Gotchas

The accent on sé is critical: se (no accent) is a reflexive/object pronoun.
Saber + infinitive = "to know how to [verb]". Don't insert cómo.
Saber ≠ conocer. Saber is for facts and skills; conocer is for being acquainted with people, places, or things (next chapter).
