A tag question presents a proposition and then asks the listener to confirm it: Wageni wamefika, sivyo? “The guests have arrived, right?” English builds a different tag from every auxiliary, subject, tense, and polarity—haven't they? wasn't it? don't you? Standard Swahili normally uses one invariant confirmation tag.
The most useful neutral tag is sivyo? A more emphatic conversational alternative is si ndiyo? Informal speech also uses eh?, while intonation alone can turn a statement into a quick check. None of these requires the finite verb to be split or inverted.
Sivyo?: the broad neutral tag
Sivyo literally relates to “not so/not in that way,” but as a tag it functions like English “right?” or “isn't that so?” It does not agree with the main clause's person, noun class, tense, or polarity.
Mratibu amewatumia washiriki wote ujumbe, sivyo?
The coordinator has sent all the participants a message, right?
Vitabu vipya vimefika maktabani, sivyo?
The new books have arrived at the library, haven't they?
Tutamaliza ukaguzi kabla ya Ijumaa, sivyo?
We will finish the inspection before Friday, won't we?
English changes hasn't he → haven't they → won't we. Swahili keeps sivyo and lets the complete finite verb express those contrasts: amewatumia, vimefika, tutamaliza.
The tag usually follows a comma in careful writing because it forms its own short intonation group:
statement + comma + sivyo + question mark
Si ndiyo?: asking “isn't that correct?”
Si ndiyo? makes the request for an affirmative confirmation more explicit. It is common in conversation and can sound more insistent than neutral sivyo?.
Ulisema tutakutana langoni saa tatu, si ndiyo?
You said we would meet at the gate at nine, isn't that right?
Hii ndiyo nakala ya mwisho iliyosainiwa, si ndiyo?
This is the final signed copy, correct?
The phrase is written as two words here: si ndiyo? A fast spoken realization may sound compressed, but careful Standard Swahili keeps the components recognizable. It is not adjusted to si yeye, si wao, or a class-specific form.
Use it when the speaker has a candidate answer and actively asks the listener to endorse it. A neutral request for new information is better expressed by ordinary yes–no intonation.
Eh? and other intonational checks
Turn-final eh? is an (informal) conversational particle. Depending on intonation, it can invite agreement, check that the listener is following, or show surprise.
Utanitumia anwani ukifika, eh?
You'll send me the address when you arrive, okay?
Kumbe tayari umemaliza kazi yote, eh?
So you have already finished all the work, huh?
Its exact sound and spelling vary in transcripts—eh, e, and lengthened ee may all be encountered across East African conversation. Treat eh? as (informal) and broadly conversational, not as a fixed tag for formal reports, contracts, or academic prose. The distribution and preferred pronunciation vary among speakers in Tanzania, Kenya, Uganda, and neighboring Swahili-using communities rather than defining one single national standard.
A proposition can also be checked with intonation alone:
Mkutano umehamishwa hadi Alhamisi?
The meeting has been moved to Thursday?
With a neutral contour, this asks whether the information is true. With surprised intonation, it echoes news the speaker has just heard. Writing supplies the question mark; no overt tag is required.
Positive and negative propositions
Because the tag is invariant, the main clause itself carries polarity.
Amina amethibitisha nafasi yake, sivyo?
Amina has confirmed her place, hasn't she?
Amina hajathibitisha nafasi yake, sivyo?
Amina has not confirmed her place, has she?
English flips the tag. Swahili does not. In the second question, sivyo? asks whether the negative proposition hajathibitisha is correct.
Bare ndiyo and hapana after a negative question can be misunderstood because speakers may affirm or reject the proposition as a whole. Repeat a short clause:
Amina hajathibitisha nafasi yake, sivyo? — Ndiyo, bado hajathibitisha.
Amina has not confirmed her place, right? — Correct, she still has not confirmed it.
Amina hajathibitisha nafasi yake, sivyo? — Hapana, amethibitisha leo asubuhi.
Amina has not confirmed her place, right? — No, she confirmed it this morning.
The full answer makes polarity unmistakable. This is more reliable than mapping ndiyo/hapana mechanically onto English “yes/no.”
Short dialogue: neutral, focused, and answered
Neutral confirmation
A: Umeweka miadi ya fundi saa tano, sivyo?
A: You scheduled the technician for eleven, right?
Focused alternative
A: Ni saa tano, si saa sita, si ndiyo?
A: It is eleven, not noon, correct?
Natural full-clause answer
B: Ndiyo, nimeweka miadi saa tano kamili, na fundi amethibitisha.
B: Yes, I scheduled it for exactly eleven, and the technician has confirmed.
The second question narrows confirmation to the time contrast. No constituent is inverted; ni saa tano and si saa sita remain ordinary copular statements followed by the tag.
Tags, open questions, and alternatives
A tag checks a proposition that already has a truth value. It does not fill an unknown who/what/when slot.
Basi litaondoka saa mbili, sivyo?
The bus will leave at eight, right?
If the time is genuinely unknown, ask Basi litaondoka lini? If two times are possible, ask Basi litaondoka saa mbili au saa tatu? A tag after an unresolved alternative—“eight or nine, right?”—confirms only the whole disjunction and does not tell the listener which option to select.
Register and regional distribution
Sivyo? is neutral and widely understood in (informal) conversation, interviews, teaching, and careful (formal) speech. It is the safest written tag. Si ndiyo? is conversational and somewhat more insistent; it also appears in rhetorical (formal) speech. Eh? is strongly (informal), and its frequency and pronunciation vary regionally across East Africa. Intonational checks are universal in conversation but can be ambiguous on the page without a question mark or enough context. None of these tags is (archaic).
Common Mistakes
Rebuilding an English auxiliary tag
❌ Mtaondoka kesho, si mtaondoka?
Incorrect — Swahili does not build 'won't you?' by repeating the finite verb after si.
✅ Mtaondoka kesho asubuhi, sivyo?
You will leave tomorrow morning, won't you?
Making the tag agree with a plural human subject
❌ Wageni wamewasili hotelini, siwao?
Incorrect — siwao means 'it is not them,' not an agreeing tag.
✅ Wageni wamewasili hotelini, sivyo?
The guests have arrived at the hotel, haven't they?
Leaving a negative confirmation answer ambiguous
❌ Hujapokea risiti, sivyo? — Ndiyo.
Ambiguous — ndiyo alone does not show clearly whether the speaker has the receipt.
✅ Hujapokea risiti, sivyo? — Ndiyo, bado sijaipokea.
You have not received the receipt, right? — Correct, I still have not received it.
Dropping tag punctuation in careful writing
❌ Ripoti iko tayari sivyo.
Incorrect as a written tag question — the tag needs separation and a question mark.
✅ Ripoti iko tayari, sivyo?
The report is ready, isn't it?
Attaching a confirmation tag to an unfilled wh-question
❌ Mkutano utaanza lini, sivyo?
Incorrect for an open time question — there is no complete proposition for sivyo to confirm.
✅ Mkutano utaanza lini baada ya mapumziko?
When will the meeting begin after the break?
Key Takeaways
- Sivyo? is the broad, invariant confirmation tag.
- Si ndiyo? asks for more explicit endorsement; eh? is informal and regionally variable.
- Intonation alone can turn a proposition into a quick check.
- Positive and negative clauses keep their own polarity; the tag does not flip or agree.
- After a negative tag, answer with a full clause so assent and rejection are unambiguous.
