An offer proposes a benefit that the speaker can provide; an invitation proposes an activity or event in which the listener may participate. Both acts concern the listener's choice, so their social force depends not only on vocabulary but also on who will act, how burdensome the proposal is, and whether refusal is genuinely possible.
Esperanto has no special “polite conjugation.” It builds offers productively from questions, the volitive -u, modal verbs, and context. The grammar of those forms is stable; how much mitigation a situation needs varies across people and communities.
For the core morphology of request and offer frames, see Requests and Offers. This page concentrates on what those frames do in an unfolding interaction.
Offer your own action with Ĉu mi …-u?
The compact pattern Ĉu mi + volitive? presents the speaker's action for the listener's approval. Its practical force is “shall I …?” even though -u more generally marks a wanted or proposed action.
Vi aspektas laca. Ĉu mi portu vian valizon ĝis la hotelo?
You look tired. Shall I carry your suitcase to the hotel?
Ĉu mi fermu la fenestron, aŭ ĉu vi volas iom da freŝa aero?
Shall I close the window, or would you like some fresh air?
The explicit mi matters. In a second-person command, the subject vi is often omitted: Fermu la fenestron. With mi, the sentence clearly offers the speaker's action rather than directing the listener.
Minimal contrast:
Portu la skatolon.
Carry the box. (a directive to the listener)
Ĉu mi portu la skatolon?
Shall I carry the box? (an offer by the speaker)
The direct imperative can be perfectly appropriate in coordinated work or an emergency. It is simply not the same speech act as an offer.
Make the listener's preference explicit
Ĉu vi volas, ke mi + -u? asks directly whether the listener wants the speaker's action. It is useful when the action affects the listener or may be unwanted. The subordinate clause needs both its subject and a volitive verb.
Ĉu vi volas, ke mi rezervu ankaŭ por viaj infanoj?
Would you like me to make reservations for your children too?
Ĉu vi volas, ke mi atendu ekstere dum vi telefonas?
Would you like me to wait outside while you make your call?
Mi povas + infinitive, se vi volas makes ability available without demanding an immediate answer. It is often less pressuring when the recipient may prefer to manage alone.
Mi povas legi la kontrakton antaŭ ol vi subskribos ĝin, se vi volas.
I can read the contract before you sign it, if you like.
The condition se vi volas is not empty decoration: it explicitly returns control to the listener. Do not attach it mechanically after an offer whose refusal would clearly be punished.
Offer food, drink, and objects
For an offered item, ordinary questions are natural: Ĉu vi volas …?, Ĉu vi ŝatus …?, or Ĉu mi donu/verŝu/alportu …? The conditional ŝatus makes the preference slightly more remote and is useful with guests or in service encounters (neutral to formal).
Ĉu vi ŝatus tason da teo antaŭ la kunveno?
Would you like a cup of tea before the meeting?
Ĉu mi verŝu al vi iom pli da akvo? — Jes, dankon, nur iomete.
Shall I pour you a little more water? — Yes, thank you, just a little.
The quantity phrase iom da akvo avoids implying a full serving. In hospitality, a contextually warm Prenu kukon can function as encouragement to accept, but grammatically it remains a directive. A question makes choice more explicit, especially when dietary, religious, or health constraints may be unknown.
The lexical verb oferti takes the offered thing as its object and normally marks the recipient with al: Mi ofertis kafon al la gastoj. In live interaction, however, Ĉu vi volas kafon? is usually lighter than announcing Mi ofertas al vi kafon.
Invite someone to an activity
Use Ĉu vi volas + infinitive? or Ĉu vi ŝatus + infinitive? for an open invitation. Include enough practical detail for a real decision.
Ĉu vi volas veni kun ni al la koncerto vendredon vespere?
Would you like to come with us to the concert on Friday evening?
Ni vespermanĝos ĉe mia frato je la sepa. Ĉu vi ŝatus aliĝi al ni?
We are having dinner at my brother's at seven. Would you like to join us?
Mi invitas vin al + event/place explicitly performs the invitation and suits written or ceremonial contexts (formal). With an infinitive, Mi invitas vin partopreni … is also possible.
Mi ĝojas inviti vin al la malfermo de la nova komunuma biblioteko la 14-an de Septembro.
I am pleased to invite you to the opening of the new community library on September 14.
For a joint suggestion, Ĉu ni + -u? asks about shared willingness, while Ni + -u proposes the action more assertively:
Ĉu ni iru al la merkato post la matenmanĝo?
Shall we go to the market after breakfast?
Ni iru al la ombro; ĉi tie estas tro varme.
Let's go into the shade; it is too hot here.
PMEG describes the question Ĉu ni iru …? as formally asking about will and commonly functioning as a polite proposal. That pragmatic force follows systematically from asking whether the shared desired action should occur.
Sequence the interaction, not just the sentence
A considerate offer often has three moves: notice a relevant situation, offer a specific action, then wait. An invitation adds practical details after interest has been shown. Giving every detail before the listener can decline may feel like pressure.
Mi vidas, ke via telefono baldaŭ malŝaltiĝos. Ĉu vi volas uzi mian ŝargilon? — Dankon, tio tre helpus.
I see that your phone is about to switch off. Would you like to use my charger? — Thank you, that would help a lot.
The first sentence makes the offer relevant; tio in the response refers to accepting the proposed help. No elaborate politeness marker is necessary.
Connectors must describe a real relation. Do introduces a consequence or next step; cetere can introduce an unrelated side offer. Compare: Pluvas, do ĉu mi veturigu vin hejmen? has a causal path. La raporto estas preta. Cetere, ĉu vi volas kafon? shifts topic.
Leave a real path to refusal
Repeated offers can show hospitality, but they can also turn a question into pressure. After one clear refusal, either accept it or make new information explicit: Ĉu vi certas? Restis senlakta supo. Do not simply repeat the same question until the socially easiest answer is “yes.”
Status matters too. A manager's “invitation” to work late may function as a request even in question form. If attendance is required, state that transparently rather than disguising an obligation as a voluntary social offer.
La vendreda kunveno estas deviga por la projektteamo; poste ĉiuj estas invititaj al neformala vespermanĝo.
Friday's meeting is mandatory for the project team; afterwards everyone is invited to an informal dinner.
That sentence separates obligation from invitation. Politeness does not require hiding institutional force.
Register and accepted variation
In everyday conversation (informal), short questions such as Ĉu vi volas kafon? and Ĉu mi helpu? are normal. Ĉu vi ŝatus …? adds distance without becoming ceremonial. Mi havas la honoron inviti vin … is possible (formal or ceremonial), but it is excessive for a message to a friend.
These are register choices, not a scale from bad to grammatically perfect. Intonation and relationship can make the short form warmer than an elaborate formula. Esperanto's lack of a T–V pronoun distinction means speakers create respect through wording, explanation, and room for response.
Invitations in writing and group channels
A written invitation should reveal who is invited, what participation involves, and when an answer is needed. In a group channel, distinguish a general announcement from a personal invitation. Ĉiuj rajtas veni announces access; Ni aparte invitas la novajn membrojn actively welcomes a group.
Ni piknikos en la urba parko dimanĉe ekde la tagmezo. Ĉiuj familianoj estas bonvenaj; bonvolu informi nin ĝis ĵaŭdo, kiom da homoj venos.
We will have a picnic in the city park on Sunday from noon. All family members are welcome; please let us know by Thursday how many people will come.
The final bonvolu is a request for logistical information, not part of the invitation itself. Keeping those acts separate helps the recipient see both the voluntary event and the practical response needed.
Remote invitations also need a medium and access information, but do not overload the opening. First invite; after acceptance, send the link, time zone, and participation details. This sequencing lowers processing cost without hiding conditions.
Common Mistakes
1. Using a request marker for the speaker's own offer.
❌ Bonvolu, ke mi portu vian sakon.
Incorrect frame: bonvolu asks the listener to be willing, while the speaker is proposing their own action.
✅ Ĉu mi portu vian sakon?
Shall I carry your bag?
2. Omitting the subject of a subordinate proposal.
❌ Ĉu vi volas, ke rezervu tablon?
Incorrect: the ke-clause must identify who should reserve the table.
✅ Ĉu vi volas, ke mi rezervu tablon?
Would you like me to reserve a table?
3. Marking the invited event with the wrong preposition.
❌ Mi invitas vin ĉe mia naskiĝtaga festo.
Incorrect for motion or participation toward an event: ĉe describes being at the location.
✅ Mi invitas vin al mia naskiĝtaga festo.
I invite you to my birthday party.
4. Using do for an unrelated offer.
❌ La filmo komenciĝas je la oka. Do, ĉu vi volas teon?
Incorrect logical link: the tea offer is not a consequence of the film's start time.
✅ La filmo komenciĝas je la oka. Cetere, ĉu vi volas teon?
The film starts at eight. By the way, would you like tea?
Key Takeaways
- Use Ĉu mi …-u? to offer your action and Ĉu vi volas, ke mi …-u? to foreground the listener's preference.
- Offer items with a preference question or a concrete action such as Ĉu mi verŝu …?
- Invite with Ĉu vi volas/ŝatus …?, Ĉu ni …-u?, or the formal Mi invitas vin al ….
- Context and power determine pressure; a question form alone does not guarantee a free choice.
