Must, may or want: keep the commitment

CEFR A2

What you will learn

  • Separate obligation, permission and stated intention in a short plan.
  • Keep absence of obligation distinct from prohibition.
  • Report a general requirement without inventing a named responsible person.

Before you start

  • Know the regular present, basic questions and noun agreement. Use the linked lessons for the forms needed here.
  • Use familiar present forms; any past question in this page can use the already studied preterite or perfect.

The idea

Tener que plus infinitive assigns an obligation to a grammatical subject: “Tenemos que reservar”. Hay que plus infinitive presents a requirement without naming that subject: “Hay que reservar”. A general requirement may apply to a stated group, but the expression itself does not identify a particular person to do it. Poder plus infinitive can express ability or permission. The context on this page labels a rule that permits an action, so “puedes entrar” reports permission. It does not establish that the listener wants to enter or has decided to do so. Querer plus infinitive reports a wish or intention: “quiero entrar”.

No tener que expresses absence of necessity; no poder, in a rule explicitly about permission, expresses that the action is not allowed. “No tienes que traer comida” does not mean food is forbidden. Read which question is answered: must it happen, may it happen, or does the person want it?

A plan can change while its permissions and obligations remain unchanged. A person may want an action that is not allowed, or decline something optional. Keep each source of information separate: the rule supplies the obligation or permission, and the person’s statement supplies the intention. These tasks do not demand probability readings of modals or later subordinate moods.

Complete present reference

tútienes quepuedesquieres

vosotros / vosotrastenéis quepodéisqueréis

The infinitive remains unchanged after these first verbs. Hay que is impersonal and has no person paradigm.

How it sounds

  • Hay que inscribirse. Celia puede asistir por internet.Registration is a requirement without a specified individual organiser. Online attendance is permitted, so it uses puede rather than a statement of desire. Celia’s preference remains unknown even though an online option is available.

Transfer 1

P1. Museum rules: «Bags: the cloakroom is optional. Food: not allowed in the galleries. Photos: allowed without flash.» P2. Ana wants to eat her sandwich in the gallery. P3. Her friend’s summary says «Ana no tiene que comer en la sala». Write the Spanish summary again: what the rules say about Ana’s bag (dejar la mochila en el guardarropa) and about eating in the gallery, then add Ana’s wish.

Answer available without interaction

Answer: Your answer: Spanish wording and any requested English comment: Ana no tiene que dejar la mochila en el guardarropa. No puede comer en la sala, pero quiere comer allí.

Model answer: Ana no tiene que dejar la mochila en el guardarropa. No puede comer en la sala, pero quiere comer allí.

Criteria for reviewing your answer:

  • Presents the cloakroom as optional (absence of obligation), not as forbidden.
  • Presents eating in the gallery as not allowed; «no tiene que comer» is rejected because it only removes an obligation.
  • Reports Ana’s wish separately and does not let it change the rule; the photo rule may be omitted.

The cloakroom rule removes an obligation; the food rule forbids an action. The draft turns the ban into mere absence of obligation. Ana’s wish comes from her, not from the rules, and the photo rule is not needed.

Transfer 2

P1. A notice says: «Visitors may reserve a seat online. Reservations are not compulsory.» P2. Luis says: «Prefiero estar de pie». P3. A friend reports: «Luis tiene que reservar porque puede reservar». Rewrite the report in Spanish in two or three sentences so that it keeps exactly what the notice says and what Luis says.

Answer available without interaction

Answer: Your answer: Spanish wording and any requested English comment: Luis puede reservar un asiento, pero no tiene que hacerlo. No quiere reservar: prefiere estar de pie.

Model answer: Luis puede reservar un asiento, pero no tiene que hacerlo. No quiere reservar: prefiere estar de pie.

Criteria for reviewing your answer:

  • Reports reserving as allowed with poder and as not required (no tener que or an equivalent), never as forbidden.
  • Takes Luis’s intention from his own words (no quiere / prefiere), not from the notice.

The notice gives a permission and removes an obligation; Luis’s preference shows that he does not want to reserve. Permission is not obligation, and neither establishes his intention.

Transfer 3

P1. A workshop sign says: «After the session: close the windows. The last person to leave turns off the lights.» P2. Julia is present; nobody knows yet who will leave last. P3. Write a Spanish message for the group noticeboard that states both requirements faithfully. Then say in English whether the sign establishes that Julia must turn off the lights.

Answer available without interaction

Answer: Your answer: Spanish wording and any requested English comment: Después de la sesión, hay que cerrar las ventanas. La última persona en salir tiene que apagar las luces. Not established: we do not know that Julia will leave last.

Model answer: Después de la sesión, hay que cerrar las ventanas. La última persona en salir tiene que apagar las luces. Not established: we do not know that Julia will leave last.

Criteria for reviewing your answer:

  • States the window requirement without naming a person (hay que; «tenemos que» for the whole group is also acceptable).
  • Assigns the lights to the last person (la última persona / la última persona en salir) with tener que and does not transfer that role to Julia.

Closing the windows is a general requirement with no named person, so an impersonal requirement fits. The lights are assigned to whoever leaves last, a role, not to Julia.

What your own language pushes you to say

Wrong No tienes que traer comida: la comida está prohibida.

Right No tienes que traer comida: no es obligatorio.

The absence of necessity does not forbid the action. A separate rule is needed to establish prohibition.

Transfer 4: combine the distinctions

P1. Plan for a class visit: «Marta reserves the room. Visitors can attend online. Printing the notes is not required. Food is not allowed in the room.» P2. Marta writes: «Me gustaría ir en persona». P3. A classmate’s summary for the visitors says: «Ustedes tienen que asistir por internet y no tienen que comer en la sala. Marta tiene que reservar la sala y tiene que ir en persona». Repair the summary in Spanish, addressing the visitors as ustedes: change only what is wrong, add the missing printing rule and keep Marta’s preference separate from the rules.

Answer available without interaction
  • Turns online attendance into a permission and food into a prohibition for ustedes (pueden / no pueden).
  • Adds that printing is not required (no tienen que), without turning it into a ban.
  • Keeps Marta’s obligation to reserve unchanged and reports her in-person plan as a wish (quiere / le gustaría), not as an obligation or a permission.

Answer: Ustedes pueden asistir por internet. No tienen que imprimir los apuntes. No pueden comer en la sala. Marta tiene que reservar la sala y quiere ir en persona.

Two claims change force: online attendance is a permission, not an obligation, and food is banned, not merely optional. Marta’s booking is already right: the plan gives that task to her. «Tiene que ir en persona» turns her wish into an obligation;«Me gustaría» reports what she wants. The printing rule was missing.
