What Does Why Mean in Spanish: Fast-Track to True Language Clarity

Pick "por" for questions about cause, "para" for questions about purpose

Posted by

TL;DR

  • "Why" in Spanish is usually "por qué" (for asking about cause or reason) or "para qué" (for asking about purpose or goal)
  • "Qué" means "what" and combines with "por" (for/because of) or "para" (for/in order to) to make different questions
  • Four forms to know: "¿por qué?" (question), "porque" (answer), "porqué" (noun), and "por que" (relative clause)
  • "¿Por qué?" asks about reasons for something that’s happened; "¿para qué?" asks about intentions or goals
  • Pick "por" for questions about cause, "para" for questions about purpose
