  • Present tense yo form: "sé" (irregular, with accent)
  • Used for knowing facts, information, or how to do something (saber + infinitive)
  • Different from "conocer" which is for familiarity with people, places, or things
  • Preterite "supe" often translates as "found out" rather than "knew"
  • Future and conditional stem: "sabr-" (sabré, sabría)
  • Present subjunctive is irregular: sepa, sepas, sepa, etc.
  • Common construction: saber + infinitive (to know how to do something)
