The prepositions "Por" and "Para"

Las preposiciones "Por" y "Para"


"Por" y "para" pueden parecer similares, pero tienen significados y usos distintos.

("Por" and "para" may seem similar, but they have different meanings and uses.)

Por vs. para: the core idea

Think of it like this:

  • por = the reason, the route/channel, or the time spent (looking back at what explains the action).
  • para = the goal, the destination, or the intended receiver (looking forward to the result).
Ask yourself… If the answer is… Use…
Why? (reason/cause) Because of… por
How? (method/channel) By/through/via… por
For how long? (duration) For… (time) por
What for? (purpose) In order to… para
For whom? (recipient) For… (person/group) para
Where to? (destination) To/towards… para

Use por when you explain the cause (why)

  • por + noun = “because of / due to”

Correct

  • Hemos cancelado la excursión por el mal tiempo. (because of the bad weather)
  • No fuimos a la playa por la lluvia. (because of the rain)

Typical mistake

  • Cancelamos la excursión para el mal tiempo. → Cancelamos la excursión por el mal tiempo.

Use por for method/channel (how)

  • por + communication channel / system = “by / via / through”

Common professional contexts

  • Reservamos el vuelo por Internet. (online / via the internet)
  • Te lo envío por correo electrónico. (by email)
  • Lo hablamos por teléfono. (by phone)

Self-check

  • If you can replace it with “via” → it is usually por.

Use por for duration (for how long)

  • por + time period = how long something lasts.
  • Hemos viajado por dos semanas. (for two weeks)
  • Nos quedamos en Valencia por tres días. (for three days)

Don’t confuse this with deadlines: duration is time spent, not a time limit.

Use para for purpose (what for)

  • para + infinitive = “in order to …”
  • He llamado a la agencia para comprar un billete. (in order to buy a ticket)
  • Estudio español para mi trabajo. (for my job / to use at work)

Quick test

  • If you can add “in order to” → choose para.

Use para for recipient (for whom)

  • para + person/group = who receives it / who it is intended for.
  • Este mapa es para los turistas. (intended for tourists)
  • Este correo es para mi jefe. (for my boss)

Mini self-check

  • If it answers “Who is the target audience / receiver?” → para.

Use para for destination/direction (where to)

  • para + destination = movement towards a goal.
  • El autobús ha salido para el aeropuerto a las 8. (for the airport)
  • El tren sale para Barcelona a las 7:30. (for Barcelona)

Typical mistake

  • El autobús sale por el aeropuerto. (sounds like “through the airport”) → El autobús sale para el aeropuerto.

One-minute decision guide (do this in your head)

  1. Is it a goal/endpoint (purpose, receiver, destination)? → para
  2. Is it an explanation/background (cause, method, duration)? → por

Checkpoint: If English uses “for”, Spanish can be por or para. Always ask the question first (why/how/how long vs. what for/for whom/where to).

  1. "Por" can express cause, motive, reason, and the duration of an action.
  2. "Para" can express the intention, aim, or purpose of an action; it indicates the recipient and the direction to a destination.
