What does Sé mean?
Sé is the first person singular (yo) form of two different verbs in Spanish: saber and ser. In the context of knowledge, Sé comes from the verb saber and means I know. Use Sé when you know facts, information, or how to do something. For example, for a fact say Sé and then the information.

To ask someone if they know, use ¿Sabes …? not a form of Sé with yo. Example: ¿Sabes dónde está el baño?
Explanation: Ask others if they know information.
Common beginner mistakes and how to avoid them
These errors are frequent and easy to fix.
Mistake 1: Using Sé from ser by accident
Fix: Check context. If you mean I know, use Sé from saber. If you mean I am, that is different but spelled the same. For example, Sé alto is wrong for I am tall; use Soy alto.
Mistake 2: Saying Yo sé before every answer
Fix: Spanish often drops yo and a simple Sé or No Sé is enough. Use full subject only for emphasis.
Mistake 3: Using saber instead of conocer for people or places
Fix: Use conocer for familiarity with people or places. Example: Conozco a María (I know María). Use Sé for facts: Sé su teléfono (I know her phone number).
