Gastar in English: Meaning, Uses, Conjugation, and Natural Translations

Author: Ilyas Baba

TL;DR

Gastar in English usually means to spend, to use up, to waste, or to wear out, depending on context.
It is used for money, time, energy, supplies, and damage from use.
The reflexive form gastarse often means to be spent, to wear out, or to use something up.
The best translation depends on what is being “gasted”: money, resources, effort, or an object.


The quick answer: what does “gastar” mean in English?

The Spanish verb gastar most commonly translates into English as “to spend.” However, it does not always mean spending money. Depending on the sentence, gastar can also mean:

  • To spend, usually money, time, or effort
  • To use up, for resources such as fuel, water, battery, or supplies
  • To waste, when something is spent badly or unnecessarily
  • To wear out, when something becomes damaged through use
  • To go through, in casual English, especially for large amounts of money or resources

A simple example is:

Gasté mucho dinero.
I spent a lot of money.

But another sentence needs a different English verb:

Este coche gasta mucha gasolina.
This car uses a lot of gas.
Also natural: This car burns a lot of fuel.

And with clothing or objects:

Los zapatos se gastaron rápido.
The shoes wore out quickly.

For learners, the key point is this: gastar does not have one fixed English translation. The natural English version depends on the noun that follows it and the idea behind the sentence.


Main meanings of “gastar in English”

1. Gastar = to spend money

This is the most common and most direct translation.

Spanish:

Ella gastó 50 euros en una chaqueta.

English:

She spent 50 euros on a jacket.

In English, the pattern is usually:

to spend + money + on + thing

Examples:

  • Gasté veinte dólares en comida.
    He spent twenty dollars on food.

  • No gastes todo tu sueldo.
    Do not spend all your salary.

  • La empresa gastó demasiado en publicidad.
    The company spent too much on advertising.

A frequent learner mistake is translating Spanish structure too literally:

Incorrect: He spent 50 euros in a jacket.
Correct: He spent 50 euros on a jacket.

English uses on for the thing purchased.


2. Gastar = to spend time

Gastar can also refer to time, although pasar is often more common in Spanish for “to spend time.” Still, gastar tiempo appears when the speaker sees time as a resource.

Spanish:

Gastó toda la tarde buscando el documento.

Natural English:

He spent the whole afternoon looking for the document.

Examples:

  • No quiero gastar tiempo en eso.
    He does not want to spend time on that.

  • Gastaron horas discutiendo.
    They spent hours arguing.

  • Gasta demasiado tiempo en redes sociales.
    She spends too much time on social media.

In English, time follows the same basic idea as money:

to spend + time + on something
to spend + time + doing something

Examples:

  • spend time on homework
  • spend time learning English
  • spend hours reading

3. Gastar = to use up resources

When gastar refers to fuel, electricity, water, battery, paper, ink, or supplies, English often uses use, use up, consume, or burn.

Spanish:

La impresora gasta mucha tinta.

English:

The printer uses a lot of ink.

More examples:

  • Este aire acondicionado gasta mucha electricidad.
    This air conditioner uses a lot of electricity.

  • El teléfono gasta batería muy rápido.
    The phone uses up battery very quickly.

  • No gastes toda el agua caliente.
    Do not use up all the hot water.

  • La moto gasta poca gasolina.
    The motorcycle uses very little gas.

In everyday English, consume is possible but sounds more formal or technical:

This machine consumes a lot of energy.

For casual speech, uses a lot of energy is usually more natural.


4. Gastar = to waste

Sometimes gastar has a negative meaning: to spend something badly, unnecessarily, or foolishly. In that case, English often uses waste.

Spanish:

No gastes tu dinero en tonterías.

English:

Do not waste your money on silly things.

More examples:

  • Está gastando su talento.
    He is wasting his talent.

  • Gastaron recursos en un proyecto inútil.
    They wasted resources on a useless project.

  • No gastes energía en discutir con él.
    Do not waste energy arguing with him.

Context decides whether gastar means neutral spend or negative waste.

Compare:

Gastó 100 euros en libros.
She spent 100 euros on books.

Neutral.

Gastó 100 euros en algo que no necesitaba.
She wasted 100 euros on something she did not need.

Negative.


5. Gastar = to wear out

When gastar refers to physical damage through use, English often uses wear out. In these cases, Spanish often uses the reflexive form gastarse.

Spanish:

Las ruedas se gastaron.

English:

The tires wore out.

Examples:

  • Mis zapatos se gastaron después de un año.
    My shoes wore out after a year.

  • La batería se ha gastado.
    The battery has run down.
    Also possible: The battery is dead.

  • La suela se gasta con facilidad.
    The sole wears out easily.

  • El lápiz se gastó.
    The pencil got used up.

For clothes, shoes, tires, tools, batteries, and materials, wear out is usually more natural than spend.

Incorrect: The shoes spent quickly.
Correct: The shoes wore out quickly.


Gastar vs. gastarse: what changes?

Spanish has both gastar and gastarse. English learners often need to understand the difference because the translation changes.

Gastar

Gastar often has a subject that spends, uses, or wastes something.

Juan gastó el dinero.
Juan spent the money.

El coche gasta gasolina.
The car uses gas.

Gastarse

Gastarse can mean that something becomes used up, consumed, or worn out. It can also mean someone spends all of something.

Se gastó el dinero.
He spent all the money.

La batería se gastó.
The battery ran down.

Los frenos se gastan con el tiempo.
The brakes wear out over time.

The reflexive form often adds a sense of completion: the money is gone, the battery is empty, the shoes are worn, or the resource has been used up.

Gastar bromas

This expression is important because it does not translate literally. Gastar una broma means to play a joke or to play a prank.

A literal translation such as they spent a joke on him is incorrect.

Depending on context:

Natural English equivalent:

Gastar vs. pasar: spending time

Spanish learners often compare gastar tiempo and pasar tiempo because both can translate as spend time in English.

Pasar tiempo

Pasar tiempo is common when the focus is experience, duration, or being with someone.

Pasó tiempo con su familia.
She spent time with her family.

Pasaron el día en la playa.
They spent the day at the beach.

Gastar tiempo

Gastar tiempo treats time more like a resource. It can sound practical, critical, or negative.

Gastó mucho tiempo en un problema pequeño.
He spent a lot of time on a small problem.

No gastes tiempo en eso.
Do not waste time on that.

A useful rule:

  • pasar tiempo = spend time, often neutral or positive
  • gastar tiempo = spend or waste time, often resource-focused

Gastar vs. gastar en: using the right preposition

In Spanish, gastar en means to spend on.

Gasta mucho en ropa.
She spends a lot on clothes.

Gastaron dinero en la casa.
They spent money on the house.

English also uses on after spend when naming the thing bought or funded.

Correct English patterns:

  • spend money on clothes
  • spend money on rent
  • spend money on travel
  • spend time on a project

When an action follows, English usually uses spend time + -ing:

Gastó dos horas estudiando.
She spent two hours studying.

Not: She spent two hours to study.


English phrasal verbs that translate “gastar”

English often uses phrasal verbs where Spanish uses gastar.

Use up

For supplies or resources:

Gastaron toda la leche.
They used up all the milk.

La máquina gastó todo el papel.
The machine used up all the paper.

Run out of

This translates the idea that someone has no more of something.

Se quedaron sin dinero is more direct for “ran out of money,” but se gastaron el dinero can mean the same result.

Se gastaron todo el dinero.
They ran out of money because they spent it all.

Wear out

For objects damaged by use:

Los neumáticos se gastaron.
The tires wore out.

Burn through

Informal English, often used for money or fuel:

Gastó todos sus ahorros en seis meses.
He burned through all his savings in six months.

This is expressive and casual. It suggests spending quickly.


Typical mistakes when translating “gastar in English”

Mistake 1: Always translating “gastar” as “spend”

Gastar often means spend, but not always.

Incorrect: This car spends a lot of gas.
Correct: This car uses a lot of gas.

Incorrect: My shoes spent.
Correct: My shoes wore out.


Mistake 2: Using the wrong preposition after “spend”

Incorrect: She spent money in clothes.
Correct: She spent money on clothes.

Incorrect: He spent two hours in homework.
Correct: He spent two hours on homework.


Mistake 3: Translating idioms word for word

Incorrect: They spent a joke on him.
Correct: They played a joke on him.

Incorrect: Do not spend saliva.

Mistake 4: Missing the negative tone

If the Spanish sentence criticizes the action, English may need waste, not spend.

He is wasting his life in a job he hates.

The word spending would sound more neutral. Wasting captures the criticism.

Pronunciation note: how “gastar” sounds

Gastar is pronounced roughly like:

gahs-TAR

The stress is on the final syllable: -tar.

The Spanish g before a sounds like the English g in go. The a vowels are open and clear, closer to ah than the English vowel in cat. The r at the end may be tapped or lightly pronounced, depending on accent and speaking style.

Learners do not need a perfect accent to be understood. Clear stress and vowel sounds matter more than imitating a specific regional accent.


Practice: translate “gastar” naturally

Try choosing the best English translation for each sentence.

Mini-guide for English speakers learning “gastar”

For English speakers learning Spanish, gastar is useful because it covers several English verbs. One Spanish verb can express:

  • spend, as in money or time
  • use, as in fuel or electricity
  • use up, as in supplies
  • waste, as in poor use of resources
  • wear out, as in shoes or tires

This makes gastar efficient in Spanish but tricky in English translation. English prefers more specific verbs. A good translator or learner does not ask only, “What does gastar mean?” The better question is, “What is being spent, used, wasted, or worn out?”

That question usually leads to the right English verb.
