What is Saber and when to use it
Saber means to know facts, information, or how to do something. It is different from conhecer, which is used for being familiar with people, places, or things. Use saber for memorized facts, learned skills, phone numbers, addresses, languages, or knowing how to perform actions.

Skills or learned abilities: cooking, driving, using software

Common beginner mistakes and how to avoid them
Mixing saber and conhecer: Use saber for facts and skills, and conhecer for familiarity with people, places, or art. Wrong: Eu sei o João to mean I know João. Correct: Eu conheço o João.
Using the infinitive incorrectly after saber: You must use the infinitive verb for skills. Wrong: Eu sei como eu cozinho. Correct: Eu sei cozinhar or Eu sei como cozinhar.
Forgetting the reflexive uses: Some verbs require saber + que or saber + de. Compare: Eu sei que ele vem (I know that he is coming) versus Eu sei do evento (I know about the event). Both are common, but remember que introduces clauses and de introduces topics.
Examples highlighting mistakes
Wrong: Eu sei o Brasil.
Correct: Eu conheço o Brasil.
English: I know Brazil (meaning I am familiar with Brazil).
Wrong: Eu sei falar português ontem.
Correct: Eu aprendi a falar português ontem or Eu já sabia falar português ontem.
English: I learned to speak Portuguese yesterday or I already knew how to speak Portuguese yesterday.
