Supongo que la lavadora está libre.

Supongo means I suppose, I guess, or I assume.

It comes from the verb suponer. In this sentence, it softens the statement and shows the speaker is not completely certain. So instead of stating a fact directly, the speaker is making a reasonable assumption.

• Supongo que... = I suppose that... / I guess that...
• It often sounds a little cautious or tentative.

For example:

• Supongo que está en casa. = I suppose he/she is at home.
• Supongo que ya comieron. = I guess they already ate.

After verbs like suponer, creer, pensar, and decir, Spanish often uses que before the next clause.

So:

• Supongo que... = I suppose that...

In English, that is often optional:

• I suppose the washing machine is free
• I suppose that the washing machine is free

In Spanish, que is normally required here.

Spanish usually uses the definite article more often than English does.

La lavadora means the washing machine. In context, it probably refers to a specific washing machine that both speaker and listener know about.

In English, you might sometimes leave out the in very informal situations, but in Spanish you normally keep the article:

• La lavadora está libre.
• El baño está ocupado.
• La mesa está limpia.

Without la, the sentence would sound incomplete or unnatural in normal usage.

Yes. Lavadora is the standard word for washing machine in most of Latin America and Spain.

A few useful related words:

• lavadora = washing machine
• secadora = dryer
• lavarropa / lavarropas = in some countries, another word for washing machine or laundry machine

For a general learner of Latin American Spanish, lavadora is the safest and most widely understood choice.

This is a very common question.

Spanish has two verbs for to be: ser and estar.

Here, está is used because libre describes a temporary state or current condition: the washing machine is available right now.

• está libre = it is free/available right now
• es libre = it is free in a more essential or permanent sense

With a machine, room, seat, bathroom, etc., if you mean available, unoccupied, or not in use, you use estar:

• El baño está libre.
• La silla está libre.
• La computadora está libre.

Using es libre here would sound wrong.

Here, libre means free, available, unoccupied, or not being used.

It does not mean free of charge in this sentence.

So la lavadora está libre means something like:

• the washing machine is available
• the washing machine is not being used
• the washing machine is free to use

Context tells you which English wording fits best.

Yes, it can be natural, especially in a shared space where people are waiting to use it.

That said, depending on the country or situation, some speakers might also say:

• La lavadora está desocupada.
• La lavadora está disponible.
• No están usando la lavadora.

So está libre is understandable and natural, but it is not the only way to say it.

Yes. Ocupada is the natural opposite here.

• La lavadora está libre. = The washing machine is free.
• La lavadora está ocupada. = The washing machine is occupied/in use.

This is a useful pair to learn:

• libre = free, available
• ocupado/a = occupied, busy, in use

Because lavadora is feminine, you use ocupada, not ocupado.

Some adjectives change for gender, and some do not.

Libre is an adjective that has the same form for masculine and feminine nouns:

• el baño libre
• la lavadora libre

But it does change for number:

• la lavadora libre
• las lavadoras libres

Compare that with an adjective that does change for gender:

• ocupado / ocupada
• el baño está ocupado
• la lavadora está ocupada

Está is the third-person singular present tense of estar.

It is used because the sentence describes the washing machine’s current condition:

• right now it is available

So:

• está = is

If you wanted a past or future meaning, the verb would change:

• estaba libre = was free
• estará libre = will be free / is probably free

Yes, in many situations.

• Supongo que la lavadora está libre.
• Creo que la lavadora está libre.

Both can mean I think/I suppose the washing machine is free.

There can be a slight difference in tone:

• supongo que often sounds a bit more like an assumption based on limited information
• creo que often sounds a bit more like a personal belief or opinion

In everyday conversation, though, they are often very close.

A careful pronunciation would be approximately:

soo-PON-go keh lah lah-bah-DOH-rah es-TAH LEE-breh

A few notes:

• g in supongo is like the English g in go
• v in lavadora is pronounced much like b in most Spanish accents
• r in libre is a light Spanish r
• stress falls on:
  • suPONgo
  • lavaDOra
  • esTÁ
  • LIbre

In natural speech, it flows together smoothly: Supongo que la lavadora está libre.

Yes, but the original order is the most neutral and natural.

Standard:

• Supongo que la lavadora está libre.

Other orders are possible for emphasis, but they are less basic:

• La lavadora, supongo que está libre.
• Supongo que está libre la lavadora. (less common, more marked)

For learners, the original version is the best pattern to remember: Supongo que + noun + está + adjective

It is neutral and works in both formal and informal contexts.

Nothing in it is especially casual or especially formal. It would sound fine:

• at home
• in an apartment building laundry room
• in a dorm
• in a shared laundry area

If you wanted to sound slightly more direct, you could say:

• Creo que la lavadora está libre.

If you wanted to sound more certain, you could say:

• La lavadora está libre.

So supongo que adds a little uncertainty, but not extra formality.
