Overview
Por is one of the most versatile and often perplexing prepositions in Spanish, a cornerstone for B1 learners navigating complex expressions. While it encompasses meanings of reason, means, duration, and movement through, this guide focuses on its indispensable role in articulating prices, costs, and exchanges. Understanding por in this context is not merely about memorizing translations; it's about grasping the underlying transactional logic it conveys.
Unlike its counterpart para, which generally indicates a destination, purpose, or recipient, por describes the exchange itself, signifying what is given or received in return, or the medium through which a transaction occurs. When you pay por something, you are providing a value in exchange for another. This distinction is fundamental for expressing financial and commercial interactions accurately.
Mastering por in these scenarios elevates your communication, allowing you to confidently discuss everything from buying groceries to negotiating a price.
How This Grammar Works
por for prices and exchanges is rooted in its inherent capacity to establish a relationship of equivalence, causation, or mediation. Linguistically, por frequently derives from the Latin pro, meaning 'for,' 'in exchange for,' or 'on behalf of.' When you use por in a transactional sense, you are essentially stating that one item, service, or amount of money is provided in return for, by means of, or as the cause of obtaining another. It's a linguistic representation of a quid pro quo.X por Y. Here, X represents the item or service being acquired or given, and Y denotes the compensatory element — the price, the equivalent item, or the motive for the exchange. The preposition por acts as the connector, articulating the reciprocal nature of the transaction.Compré una casa por doscientos mil euros (I bought a house for two hundred thousand euros), doscientos mil euros (Y) is the value that facilitates the acquisition of una casa (X). The euros are the medium or cause for the purchase.para, which would suggest a purpose or destination, such as El dinero es para comprar una casa (The money is for buying a house). Here, para indicates the purpose of the money, not what is given in exchange. With por, you're always looking at the value exchanged or the reason/means behind the transaction.Formation Pattern
por in contexts of prices and exchanges is consistent and adaptable. It typically involves a verb of transaction, followed by the item or service being transacted, then the preposition por, and finally the price, the equivalent item, or the reason underpinning the exchange. The flexibility of this pattern lies in which elements you choose to explicitly state.
Verb of Transaction + [Item/Service Exchanged] + [Price/Equivalent Item/Reason]
Comprar | Compré un coche por diez mil euros. | Compré un carro por diez mil dólares. | I bought a car for ten thousand euros/dollars. |
Vender | Vendimos el piso por doscientos mil euros. | Vendimos el departamento por doscientos mil dólares. | We sold the apartment for two hundred thousand euros/dollars. |
Pagar | Pagué por la cena anoche. | Pagué por la comida anoche. | I paid for dinner last night. |
Cambiar | Te cambio mi móvil por tu tablet. | Te cambio mi celular por tu tablet. | I'll trade my mobile for your tablet. |
Alquilar | Alquilamos la casa por ochocientos euros al mes. | Alquilamos la casa por ochocientos dólares al mes. | We rented the house for eight hundred euros/dollars a month. |
Sustituir | Sustituimos el aceite por uno ecológico. | Sustituimos el aceite por uno ecológico. | We substituted the oil for an ecological one. |
por consistently introduces the value received, the cost incurred, or the substitute item as part of the exchange. When asking about a price, you'll use ¿Por cuánto...? (For how much...?). For example, ¿Por cuánto vendes tu bici? (For how much are you selling your bike?). This structure clearly links the item (tu bici) with the requested compensatory value.
When To Use It
Por is indispensable across several distinct scenarios involving transactions, costs, and exchanges. Each application reinforces its core meaning of establishing a reciprocal relationship or defining a measure of value.- 1To Express Price, Cost, or Value (In Exchange For):
por's most direct and frequent application in commercial contexts. When you specify the monetary amount paid or received for an item or service, por signifies "in exchange for." It acts as the bridge connecting the item with its monetary equivalent.Compré este cuadro por cien euros.(I bought this painting for one hundred euros.) Here,cien eurosrepresents the direct payment given to acquireeste cuadro. You're getting the painting in return for the euros.¿Por cuánto vendes tu teléfono?(For how much are you selling your phone?) The phrase¿Por cuánto...?directly asks for the price that will be given in exchange for the phone.Pagaron demasiado por el café.(They paid too much for the coffee.)Demasiado(too much) indicates the cost incurred in exchange for the coffee.
- 1To Indicate Exchange, Trade, or Substitution (In Place Of):
por functions as "in exchange for" or "in place of." This highlights a literal or figurative substitution.Te cambio mi bolígrafo por el tuyo.(I'll swap my pen for yours.) This signifies a direct trade, withporlinking the two items in a reciprocal exchange.Trabajo por mi compañero esta noche.(I'm working for my colleague tonight.) Here,pordenotes substitution; you are literally taking your colleague's place or performing a task on their behalf. This is a common phrase in work settings.Ella me dio su asiento por el mío en la ventana.(She gave me her seat for mine by the window.) This clarifies a direct exchange of items—her seat for your seat.
- 1To Express Rates, Ratios, or Per-Unit Measurements ("Per" or "A"):
Por is essential when conveying "per" or "a" in descriptions of rates, frequency, or proportions. This extends the idea of value or measure divided into units.Cuesta diez euros por persona.(It costs ten euros per person.)Porestablishes the rate for each individual unit (person).Conduzco a cien kilómetros por hora.(I drive at one hundred kilometers per hour.) This indicates speed measuredperunit of time.El veinte por ciento de la población.(Twenty percent of the population.)Por ciento("percent") is a fixed phrase whereporconsistently means "per" (hundred).
- 1To Express Gratitude (Thanks For Something):
por indicates the reason or the motive for which you are grateful. It signifies what you are thanking in return for. While not a financial transaction, it's an exchange of sentiment for a favor or action.Gracias por tu ayuda.(Thanks for your help.) Your gratitude is given in return for their assistance.Gracias por invitarme a la fiesta.(Thanks for inviting me to the party.) The invitation is the specific action or cause for the thanks.¿Te doy las gracias por el regalo?(Should I thank you for the gift?) This asks if gratitude is due because of the gift.
- 1With the Verb
Pagar(To Pay):
pagar (to pay) merits specific attention. While you can often omit por when the direct object is the specific amount paid (e.g., Pagué veinte euros), por is almost always used when pagar means to pay for something, emphasizing the item or service being acquired.Pagué por la cena.(I paid for dinner.) Here, the focus is on the object (la cena) for which the payment was rendered.¿Quién va a pagar por esto?(Who is going to pay for this?) The question centers on who will cover the cost associated withesto.- In a more figurative sense,
Paga por tus pecados(Pay for your sins) still implies a consequence or exchange for an action.
Common Mistakes
por in transactional contexts. Learners often make errors due to direct translation from English, or by confusing por with para or other prepositions.- 1Confusing
PorwithParafor Prices and Exchanges:
- Incorrect:
Pagué cien euros para el libro.(I paid one hundred euros for the purpose of the book.) This implies the euros are destined for the book, rather than being the cost of the book. - Correct:
Pagué cien euros por el libro.(I paid one hundred euros in exchange for the book.) Here,porclearly indicates the price given. - Rule: Remember,
paraindicates a destination, purpose, or recipient.Porindicates the exchange, reason, means, or motive. When discussing payment or trade, you're always talking about what is given in return or as a medium, hencepor. - Example of differentiation:
Compré un regalo para mi madre.(I bought a gift for my mother –paraindicates the recipient/purpose.)Compré un regalo por veinte dólares.(I bought a gift for twenty dollars –porindicates the price/exchange.)
- 1Omitting
PorwithPagarWhen Referring to an Item:
pagar can sometimes be transitive with the amount (Pagué veinte euros), you generally must use por when the object of payment is the item or service itself.- Incorrect:
Pagué la cena.(I paid the dinner.) This sounds like the dinner itself was the payment, not the object being paid for. - Correct:
Pagué por la cena.(I paid for the dinner.) This explicitly clarifies that the payment was made to acquire or cover the cost of the dinner. - Exception: When the specific price is the direct object,
poris often omitted:Pagué veinte euros.(I paid twenty euros.) However, if you are emphasizing the thing you paid for,poris usually preferred for clarity.
- 1Incorrectly Using
PorforPerExpressions that Don't Involve Rates:
por means "per" in rates like por hora or por ciento, it's not a universal equivalent for English "per" when it implies distribution or each individual item in a group without a rate.- Incorrect:
Hay tres caramelos por niño.(There are three candies per child.) This phrasing is unnatural;para cada niñoor simply describing the distribution is more common. - Correct/Natural:
Hay tres caramelos para cada niño.(There are three candies for each child.) Here,paraexpresses destination/recipient for each child. - Rule: Use
porforperonly when expressing a rate or a ratio over time, distance, or a percentage.
- 1Over-Generalizing
Porfor Every Instance of English "For":
por and para both translate to "for," learners often default to one or the other. It's crucial to analyze the underlying meaning of "for" in the English sentence.- If "for" means "because of," "on behalf of," "in exchange for," "by means of," or a duration, use
por. - If "for" means "purpose," "destination," "recipient," or a deadline, use
para. - Example:
Necesito dinero por la comida.(Incorrect; implies money by means of food).Necesito dinero para la comida.(Correct; money for the purpose of food).
