Even after taking 4 years of college Spanish and living abroad, I still don't have a very firm control of when to use por or para. What are the basic rules on when to use either.

    The "basic" rules will get you lost--you need the complete rule set to learn mastery of this concept. :)

From here (with minor corrections by me):

Uses for por:

Expressing movement along, through, around, by or about:

Anduve por las calles de la ciudad.

I walked through the streets of the city.

Denoting a time or duration when something occurs.

Viajamos por tres semanas.

We're traveling for three weeks.

Expressing the cause (not the purpose) of an action:

Me caí por la nieve.

I fell down because of the snow.

Meaning per:

Dos por ciento.

Two percent.

Meaning supporting or in favor of:

Trabajamos por los derechos humanos.

We work for human rights.

Introducing the agent of an action after a passive verb:

Fue escrito por Bob Woodward.

It was written by Bob Woodward.

Indicating means of transportation:

Viajaré por avión.

I will travel by plane.

Used in numerous expressions:

Por ejemplo.

For example.

Por favor.


Uses for para:

Meaning for the purpose of or in order to:

Para bailar la bamba, se necesita una poca de gracia.

In order to dance the bamba you need a little grace.

With a noun or pronoun as object, meaning for the benefit of or directed to:

Es para usted.

It's for you.

Meaning to or in the direction of when referring to a specific place:

Voy para Europa.

I'm heading to Europe.

    +1 for "La Bamba"! But -1 for an answer that is nothing more than copy-paste.

    I personally think copying is fine if it is stated as such and answers the question.

    The problem with an answer that is entirely a quote--especially in a case like this--is that it means the question is "general reference." This answer comes from the second google hit for "por vs para"

    In Spain "Viajamos por tres semanas" and "Viajaré por avión" are wrong. In Spain we say "Viajamos durante tres semanas" and "Viajaré en avión"

para indicates direction or intention

por indicates origin or cause

A Spanish teacher explained the difference with an "intention arrow". In the case of 'para', the intention moves from the subject to the direct object:

Las flores son para ti.     flores -> ti
Yo trabajo para ti.         yo -> ti          [I work for/to please you] or [you are my boss]

In the case of 'por', the intention moves from the direct object to the subject. This requires a little more imagination and liberal interpretation of "intention."

Yo trabajo por ti.          yo <- ti          [I work in your place] or [I work because of you]
Yo voy por camión.          yo <- camión
Yo ando por la ciudad.      yo <- ciudad
Tú me llamas por teléfono.  tú <- me
Él pasa por mí.             él <- yo
  • "Yo trabajo por ti" may also mean "I'm working for you" and "I'm working because of you"

  • To add to @skan comment "yo trabajo por ti" could mean "for you", "because of you" or "instead of you". Also I think that "tu me llamas por teléfono" should have "tu <- teléfono" in front to keep with your logic of subject<-object/complement. Am I right Flimzy? (Good answer +1)

I know this is old but I'd like to add my answer as well. The lists have been taken from a grammar textbook but most examples (except the last two) are not just pasted... sometimes I needed some help with the structure or ideas, though. :) So if you spot a mistake, feel free to correct.

Before you can choose between por and para you need to know what aisle of the Spanish supermarket you're on.

These are the only five confusing aisles, the ones that contain both por and para:

  • Purpose (para) vs. Reason (por)
  • Normal recipient (para) vs. Favor recipient (por)
  • Moment in time (para) vs. Amount of time (por)
  • Destination (para) vs. Route (por)
  • Opinion (para) vs. Indifference (por)

If you're not in any of these five aisles (or if you are, but para doesn't fit), use por.

    Una vez más, gran respuesta nachocab. He eliminado la referencia a tu enlace, pues éstos son admitidos si se utilizan junto con los fragmentos correspondientes, para así tener respuestas auto contenidas. En caso contrario, ocupan espacio que puede pasar a ser superflua (e incluso molesta) si el enlace deja de funcionar. Por supuesto, puedes recuperar el enlace si añades las partes de éste que consideres de especial relevancia para contestar esta pregunta.

    Sí, puedes. El truco aquí es preguntarse: si el enlace deja de funcionar, ¿sigue siendo válida la publicación? ¿aporta algo al sitio el enlace en sí? Si la respuesta es que sí, adelante. Por tanto, añade el enlace junto con la parte fundamental de la página que enlaza y que resulte relevante y útil para contestar la pregunta. Si no, parece publicidad :)

To put the Por or Para question into something easier to remember, I have put the reasons (taken from Puntos de Partida Spanish Textbook) in a visual style similar to Flimzy's arrows of intention, but with a few additions on the Por side.

Por is represented by a backwards arrow to represent the following meanings:

         Because of,
         Due to

Por is represented by a circle with an arrow running through it for the following meanings:

         Duration, (length of time pictured by the part of the arrow inside the circle)
         By means of,

Por is represented by a recycle symbol for the following meanings:

          In exchange for,
          In place of

Para is represented by a forward pointing arrow:

        In order to, 
        To be used for,
        To be given to,
         Future deadline,
        In the employ of,

(One meaning of para that doesn't fit with the forward arrow is "in comparison with others in the group." I don't have a picture for that one.

If anyone knows how to put visuals in here to help with this explanation, please let me know. It would look better with the circles and arrows actually drawn in. I'm very new to this.

    You can do the diagram in the tool of your choice, put the image somewhere public (dropbox folder, imgur, any image hosting site) and then link to it from here. Feb 27, 2012 at 17:36

una diferencia esencial podemos decir que es que:

  • Por: indica una razón por ejemplo por ti por alguien etc.

  • Para: indica hacia algo o para algo es decir para ti para nosotros
