Grammar Focus — Why These Three? (3 min)

Obligation
Spanish uses tener que and deber. English splits this into have to (an outside rule) and must (the speaker’s own strong rule).
Prohibition ≠ No Obligation
mustn’t = prohibido. don’t have to = no hace falta. They look similar and mean opposite things — this is the trap of the lesson.
Advice
should / shouldn’t = deberías / no deberías. Not a rule, just the best idea — the polite way to help a colleague or a guest.
One rule to remember all lesson: after must, mustn’t and should the verb has no toYou must show your passport. Only have keeps it: You have to show your passport.

Spanish Speaker Pitfalls — Avoid These Four (3 min)

1
No to after must / should: “You must to show your boarding pass” ✗
You must show your boarding pass. (must + verb, nothing between)
2
Third person needs has: “He have to wear a badge” ✗
He has to wear a badge. (have to changes; must never changes)
3
Questions need do:Have I to book a table?” ✗
Do I have to book a table? (have to is a normal verb in questions)
4
must has no past: “I must go to the airport early yesterday” ✗
I had to go to the airport early yesterday. (the past of both is had to)

Airport Security — Model Dialogue (4 min)

Officer: Next, please. You have to put your bag in the tray. El siguiente, por favor. Tiene que poner la bolsa en la bandeja.
Traveller: Of course. Do I have to take off my belt? Por supuesto. ¿Tengo que quitarme el cinturón?
Officer: Yes, you do. And you must take your laptop out of your hand luggage. Sí. Y tiene que sacar el portátil del equipaje de mano.
Traveller: What about my jacket? Do I have to take it off too? ¿Y mi chaqueta? ¿También tengo que quitármela?
Officer: No, you don’t have to take off your jacket. But you mustn’t carry liquids over 100 millilitres. No, no hace falta que se quite la chaqueta. Pero no puede llevar líquidos de más de 100 mililitros.
Traveller: Understood. Should I put my phone in the tray as well? Entendido. ¿Debería poner el móvil en la bandeja también?
Officer: Yes, that’s a good idea. You should keep your boarding pass in your hand. Sí, es buena idea. Debería llevar la tarjeta de embarque en la mano.

Security Rules — Choose the Right Form (3 min)

Click the dashed gap to check the answer. Think first: is it a rule, a prohibition, or not necessary?
1. You have to show your boarding pass at the gate. — it is the airport’s rule
2. You mustn’t use your phone during take-off. — prohibido
3. You don’t have to print your ticket — the app is enough. — no hace falta
4. You should arrive two hours before an international flight. — advice, not a rule

Airport Security — Role-Play 1 (4 min)

PAIR PRACTICE ROLES:
Student A: Security Officer. Tell the traveller what they must and must not do. STUDENT A SPEAKS FIRST.
Student B: Traveller with a laptop, a jacket and a bottle of water.
Student A (Officer): "You must take your laptop out of your bag."
Student A (Officer): "You cannot take that bottle of water through."

The Big Three — must / have to / should (3 min)

have to
An outside rule — the airport, the hotel, the company decides.
We have to check out before eleven.
must
A strong rule, often written on signs and notices.
Passengers must keep their bags with them.
should
Advice. Not a rule — just the best idea.
You should book a taxi the night before.
In everyday speech have to is far more common than must. If you are unsure which to use, have to is almost always safe — and it is the only one with a past form: had to.

The Trap — mustn’t vs don’t have to (3 min)

These two look like the same negative. They mean opposite things.

mustn’t = PROHIBIDO

There is a rule against it. Doing it is a problem.
You mustn’t smoke in the room. — no se puede fumar
You mustn’t take photos in here. — está prohibido

don’t have to = NO HACE FALTA

There is no rule. You can do it if you want — it is simply not necessary.
You don’t have to tip in this country. — no hace falta
You don’t have to bring towels. — ya están incluidas
Why Spanish speakers mix these up: Spanish no tienes que sounds like you must not, but it means you don’t have to. For a real prohibition Spanish says no debes or no se puede. Say “you mustn’t pay” to a guest and you have told them paying is forbidden.

Student B (Host): "No, you don’t have to do that. But you mustn’t leave the balcony door open."
