Future of probability: estará en casa — he's probably at home

You already know the future tense: estaré, tendrá, será — for what will happen later (B1, units 2 and 3). The same form has a second job, and it's not about the future.

Why you need it. You're waiting at a door, the owner is late, and you wonder: "Where is he? Probably stuck in traffic." A Spanish speaker says this with the future tense: ¿Dónde estará? Estará en un atasco. It's about what's true now — the speaker just doesn't know for sure and is guessing.

I know for sure — present tenseI'm guessing — future tense
Está en casa. — He's at home.Estará en casa. — He's probably at home.
Son las diez. — It's ten o'clock.Serán las diez. — It's probably about ten.
Tiene cuarenta años. — He's forty.Tendrá unos cuarenta años. — He's probably about forty.

There are no new forms: the endings and the irregular stems (tendr-, saldr-) are the same as in B1. You don't add a word for "probably": it's already in the verb form. In English you add probably, I guess or I wonder.

In a question this future means "I wonder…". You don't expect an answer — you're thinking out loud:

  • ¿Quién será a estas horas? — Who could that be at this hour?
  • ¿Cuánto costará este piso? — I wonder how much this apartment costs.
  • No contesta. Estará durmiendo. — He's not answering. He's probably asleep.
  • El vecino no sale nunca. Trabajará en casa. — The neighbor never goes out. He probably works from home.

Compare with English. English sometimes does the same thing: the doorbell rings and you say "That'll be the delivery guy." In English it's occasional; in Spain it's the everyday way to say "probably".

Future or guess? The situation decides. Mañana estará en casa — tomorrow he'll be at home: there's a word about the future. Hay luz: estará en casa — the light is on, so he's probably at home now.

A common mistake is to hear Tendrá unos cuarenta años and understand "he'll be forty". It's not about his age in the future: someone is estimating it by looking at him.

deber de + infinitive: must — a conclusion from a clue

You already know deber + verb — "should, have to": debes descansar (A1, unit 12). Add a small de and the meaning changes: it's no longer a duty but a guess.

Why you need it. The future of probability means "probably". Deber de is more confident: "must". You use it when you see a clue and draw a conclusion from it: the light is on, you hear footsteps, there's a new name on the mailbox. English "must" works the same way: "The light's on — he must be home."

How to form it: deber in the right person + de + infinitive. Only deber changes: debo de, debes de, debe de, debemos de, debéis de, deben de. After de there's always an infinitive, never que.

  • Hay luz en la ventana: debe de estar en casa. — The light's on in the window: he must be home.
  • Tiene llave del portal: debe de ser un vecino. — He has a key to the building entrance: he must be a neighbor.
  • Llevas todo el día buscando piso. Debes de estar cansada. — You've been looking for an apartment all day. You must be tired (to a woman).
  • No abren. No debe de haber nadie. — They're not opening the door. There must be nobody home.

Compare — a small de changes the meaning:

PhraseWhat it means
Debe de estar en casa.He must be at home — that's my guess.
Debe estar en casa a las diez.He has to be home at ten — that's the rule.

What you'll hear. In everyday speech people often drop the de and say a guess the same way as a duty: Debe ser el dueño — he must be the owner. The conversation makes the meaning clear, just like English "must" can be a rule ("you must pay") or a guess ("he must be the owner"). In your own Spanish, keep the rule: a guess takes de, a duty doesn't.

A common mistake is to put de into a duty:

  • ✗ debes de pagar el alquiler
  • debes pagar el alquiler — you have to pay the rent

Future or deber de? Estará en casa — just a guess. Debe de estar en casa — a conclusion: I see the light, I hear music. Very often either one works.
