Por vs para in Spanish

Common mistakes
- Translating “for” directly. English “for” splits into both words — decide goal vs motive instead.
- “Gracias para…” is wrong. Gratitude always takes gracias por.
- Purpose + infinitive. Use para: para practicar, never por practicar.
- Time. Duration uses por (por un mes); a deadline uses para (para el lunes).
- Passive voice. The doer takes por: Fue escrito por Cervantes.

Questions learners ask
- What is the difference between por and para?
- Para points forward — destination, purpose, recipient, deadline. Por looks back — cause, exchange, duration, route or means.
- Do you say “gracias por” or “gracias para”?
- Always gracias por: you are naming the reason for your thanks — gracias por tu ayuda.
- Is it “por qué” or “para qué”?
- ¿Por qué? asks about the cause (“why?”). ¿Para qué? asks about the purpose (“what for?”).
- Which one means “for”?
- Both do, depending on the sentence. Stop translating and ask whether you are giving a goal (para) or a motive, exchange or route (por).
