Esperanto does not automatically move a verb one step into the past merely because a report begins with diris “said” or pensis “thought.” In genuine indirect speech or thought, preserve the form that represented the original speaker's viewpoint. Thus Ŝi diris, ke ŝi estas laca reports her original Mi estas laca, even if the reporting happens later.
The six verb endings are invariant across person and number: -as, -is, -os express real present, past, and future, while tenseless -us, -u, and -i express imagined, volitive, and infinitive meanings. Backshift changes none of them. The reported clause still supplies its own subject where required, and its verb keeps the same complements and object pattern; only references such as mi → ŝi may need adjustment.
The core rule: preserve the original verb form
English normally backshifts “I am tired” to “she said that she was tired.” Esperanto changes the pronoun but keeps present -as.
Lina diris: ‘Mi estas laca.’
Lina said: ‘I am tired.’
Lina diris, ke ŝi estas laca.
Lina said that she was tired at the time of speaking.
The form estas is relative to Lina's act of speaking. It does not necessarily assert that she remains tired at the later reporting time.
The same preservation applies across the system:
| Original viewpoint | Direct words | Indirect report |
|---|---|---|
| simultaneous/current | Mi laboras. | Li diris, ke li laboras. |
| earlier | Mi laboris. | Li diris, ke li laboris. |
| later | Mi laboros. | Li diris, ke li laboros. |
| imagined | Mi laborus. | Li diris, ke li laborus. |
| wanted/requested | Laboru! | Li petis, ke ŝi laboru. |
Present relative to a past report
An -as form after a past reporting verb represents what was current within the original words or thought.
Marta telefonis kaj diris, ke ŝi bezonas helpon.
Marta called and said that she needed help.
La kuracisto klarigis, ke la vundo ne estas grava.
The doctor explained that the wound was not serious.
These reports preserve Mi bezonas helpon and La vundo ne estas grava. Whether those situations still hold now is a separate factual question.
— Ĉu ŝi diris, ke ŝi ankoraŭ loĝas en Liono? — Jes, tion ŝi diris hieraŭ.
— Did she say that she still lived in Lyon? — Yes, she said that yesterday.
English's past “lived” does not license Esperanto -is here. Ŝi diris, ke ŝi loĝis en Liono would naturally report an original past statement such as Mi loĝis en Liono—a residence already earlier than her speaking.
Ŝi diris, ke ŝi loĝas en Liono.
She said, ‘I live in Lyon.’
Ŝi diris, ke ŝi loĝis en Liono.
She said, ‘I lived in Lyon.’
This minimal contrast is central: the subordinate ending preserves the original temporal relation, not the English reporting tense.
Past and future relative to the original viewpoint
Past -is in a report places an event before the original speech or thought.
Omar klarigis, ke li jam sendis la fakturon.
Omar explained that he had already sent the invoice.
His likely original statement was Mi jam sendis la fakturon. English adds “had”; Esperanto keeps simple -is. A compound form such as estis sendinta is possible when the phase relation needs special emphasis, but it is not required merely because two past levels coexist.
Future -os places an event after the original viewpoint.
Ili promesis, ke ili pagos ĝis vendredo.
They promised that they would pay by Friday.
Ŝi demandis, ĉu mi venos al la kunveno.
She asked whether I would come to the meeting.
The preserved future remains -os even if the predicted event is already past when the report is retold:
Lunde Ana diris, ke ŝi venos marde, sed finfine ŝi ne venis.
On Monday Ana said that she would come on Tuesday, but in the end she did not come.
Tuesday may now be over, but venos still represents the future from Ana’s Monday viewpoint. English “would” in these examples is a backshifted future, not a hypothetical conditional. Esperanto therefore uses -os, not -us.
Conditional and volitive forms also remain themselves
Backshift concerns viewpoint, not just tense. If the original thought was hypothetical, keep -us.
Nora diris, ke ŝi helpus, se ŝi povus.
Nora said that she would help if she could.
The original could be Mi helpus, se mi povus. Both forms are imagined and timeless in themselves; context places the imagining in the past.
Requests, wishes, and commands reported through a ke-clause use -u because the subordinate action is wanted rather than asserted as factual.
La instruisto petis, ke ni sendu la taskon antaŭ lundo.
The teacher asked us to send the assignment before Monday.
Ŝi insistis, ke neniu tuŝu la aparaton.
She insisted that nobody touch the device.
Do not replace -u with -is simply because petis or insistis is past. The forms express different moods: the request happened; the requested action was wanted.
What counts as indirect speech or thought?
The rule applies when a clause reproduces the content of speech, a question, a thought, a belief, a decision, a hope, or a comparable mental message. Typical framing verbs include diri, demandi, pensi, kredi, opinii, promesi, and decidi.
Mi pensis, ke la vendejo estas malfermita dimanĉe.
I thought that the shop was open on Sundays.
The -as form preserves the thought La vendejo estas malfermita dimanĉe. It presents the opening hours as the content believed then, whether or not the belief was correct.
Not every subordinate clause after a past verb is reported content. A narrator may simply describe an observed past situation from the narrator's timeline.
Mi rimarkis, ke la pordo estis neŝlosita.
I noticed that the door was unlocked.
Here the narrator locates the door's state in the past scene. The clause is an observation described as a past fact, not necessarily a preserved inner sentence La pordo estas neŝlosita. This boundary genuinely requires interpretation; the conjunction ke alone does not decide it.
The practical test is communicative: can you naturally reconstruct exact or near-exact words or thought? If yes, preservation is likely. If the clause simply supplies the narrator's factual description, choose tense from the narrator's timeline. The neighboring page on tense in subordinate clauses develops that contrast.
Time and place words may still change
Preserving the verb ending does not mean copying every word mechanically. Pronouns must track participants, and expressions such as hodiaŭ, morgaŭ, hieraŭ, ĉi tie, and nun may need adjustment to avoid pointing to the wrong day or place.
Lunde ŝi diris: ‘Mi ne laboros hodiaŭ.’
On Monday she said: ‘I won't work today.’
Lunde ŝi diris, ke ŝi ne laboros tiun tagon.
On Monday she said that she would not work that day.
The future -os stays because it was future from her original viewpoint; hodiaŭ becomes tiun tagon because the report is made from another day.
If no confusion is possible, speakers often retain the original temporal expression. That is accepted variation, but the pedagogical recommendation is to change deictic words whenever their reference could be misread.
Nested reports preserve each represented viewpoint in turn:
Petro diris, ke Marta pensas, ke la trajno alvenos malfrue.
Petro said that Marta thought the train would arrive late.
At each reporting verb, reconstruct whose “now” the following clause represents. Several nested levels are grammatical but cognitively heavy; split the report or identify each source explicitly when the viewpoint becomes difficult to recover.
Common Mistakes
Backshifting a preserved present
❌ Li diris, ke li bezonis ripozon.
Incorrect if his original words were ‘Mi bezonas ripozon’ — -is changes the reported content.
✅ Li diris, ke li bezonas ripozon.
He said that he needed a rest.
Translating reported “would” with -us
❌ Ŝi promesis, ke ŝi revenus baldaŭ.
Incorrect if she promised ‘Mi revenos baldaŭ’ — this is reported future, not a hypothesis.
✅ Ŝi promesis, ke ŝi revenos baldaŭ.
She promised that she would return soon.
Replacing a requested action with past fact
❌ La kuracisto rekomendis, ke mi ripozis.
Incorrect — the resting was recommended, not asserted as a past fact.
✅ La kuracisto rekomendis, ke mi ripozu.
The doctor recommended that I rest.
Preserving a time word when its reference changes
❌ Pasintan lundon ŝi diris, ke ŝi venos morgaŭ.
Misleading if the visit was planned for Tuesday of last week — morgaŭ now points to tomorrow.
✅ Pasintan lundon ŝi diris, ke ŝi venos la sekvan tagon.
Last Monday she said that she would come the following day.
Key Takeaways
- Genuine indirect speech and thought preserve the original -as, -is, -os, -us, or -u form.
- A preserved -as is simultaneous with the original viewpoint, not necessarily with the later report.
- Reported English “would” normally corresponds to -os when the original had “will.”
- The rule does not govern every subordinate clause; factual narration uses the narrator's timeline.
- Pronouns and deictic time or place expressions may need adjustment even while the verb ending stays unchanged.
