Negative Questions | Swahili Grammar

A negative yes–no question uses the same negative predicate as a statement, but question intonation, a question mark in writing, or optional Je, makes it interrogative: Hujafika? can mean “Haven’t you arrived?” or “You haven’t arrived?” The form itself is straightforward; the harder part is understanding why the speaker chose negative wording and answering without mechanically copying English yes and no.

Negative questions often reveal an expectation. A speaker may be surprised that an expected event has not happened, seek confirmation of a suspicion, make a tentative offer, or challenge something just said. Unless marked otherwise, the forms below are neutral in (informal) conversation and (formal) Standard Swahili.

Build the negative predicate first

Swahili does not create a negative question by placing a free word meaning not beside an unchanged affirmative verb. Each tense has its own negative replacement. The question then uses that complete negative form unchanged.

Affirmative question	Negative question	Analytic change
Unaenda?	Huendi?	u-na-end-a → hu-end-i
Ulifika?	Hukufika?	u-li-fik-a → hu-ku-fik-a
Umefika?	Hujafika?	u-me-fik-a → hu-ja-fik-a
Utafika?	Hutafika?	u-ta-fik-a → hu-ta-fik-a

Only the present negative changes final -a to -i and removes -na-. Past negative replaces -li- with -ku-; perfect negative replaces -me- with -ja-; future negative keeps -ta- but uses the negative subject form. The hyphens are analysis only: write huendi, hukufika, hujafika, and hutafika as single words.

Unaenda nasi baada ya kazi? — Huendi nasi baada ya kazi?

Are you going with us after work? — Aren't you going with us after work?

Ulipokea ujumbe wangu? — Hukupokea ujumbe wangu jana?

Did you receive my message? — Didn't you receive my message yesterday?

Umefika kituoni? — Hujafika kituoni bado?

Have you arrived at the station? — Haven't you arrived at the station yet?

Mtafungua duka kesho? — Hamtafungua duka kesho?

Will you all open the shop tomorrow? — Won't you all open the shop tomorrow?

Mabasi hayajafika kituoni bado?

Haven't the buses arrived at the station yet?

The class 6 subject mabasi selects haya- in the negative perfect: haya-ja-fik-a. Negative questions therefore preserve noun-class agreement just as negative statements do.

💡

First conjugate the statement you are asking about. If the statement is Hujafika bado, the yes–no question is simply Hujafika bado? Question force does not create a second negative slot.

What the negative wording suggests

An affirmative question such as Umefika? is relatively open: the speaker asks whether arrival has happened. Hujafika? presents non-arrival for confirmation. Context and intonation decide whether that presentation sounds surprised, concerned, impatient, or merely confirmatory.

A violated expectation

The speaker expected the positive event and has just discovered evidence to the contrary.

Hujafika? Nilidhani treni yako iliingia saa mbili.

You haven't arrived? I thought your train came in at eight o'clock.

Hamjakula? Niliwaachia chakula jikoni tangu mchana.

You haven't eaten? I left food for you in the kitchen at lunchtime.

In both exchanges, -ja- presents the event as not yet completed. The following sentence makes the positive expectation explicit.

Confirmation of a suspicion

The speaker may already believe the negative proposition and seek confirmation.

Hutatumia gari leo, sivyo? Nitaomba funguo basi.

You won't use the car today, right? Then I'll ask for the keys.

Bado hawajakutumia ankara? Ndivyo nilivyohisi.

They still haven't sent you the invoice? That's what I suspected.

The adverb bado strengthens the “not yet” interpretation. A final sivyo? explicitly asks “is that not so?” and is more overtly confirmation-seeking than intonation alone.

Speakers also use spaced si ndiyo?, especially when the confirmation is articulated carefully, and contracted sindiyo? in conversation. All three forms can seek agreement. Sivyo? is compact and broadly usable; the conversational spelling sindiyo? is better suited to dialogue than to formal prose.

A tentative offer or challenge

A negative question can invite a positive response—roughly “Wouldn't you like…?”—or press the listener to recognize something obvious. Tone and relationship matter more here than the morphology.

Hutaki chai kidogo kabla hujaondoka?

Wouldn't you like a little tea before you leave?

Huoni kwamba mlango huu umefungwa?

Can't you see that this door is locked?

Hukai nasi kidogo baada ya chakula? — Asante, nitakaa kwa muda.

Won't you stay with us for a while after the meal? — Thank you, I'll stay for a while.

The questions with hutaki and hukai can be hospitable and gentle. A courteous refusal such as Asante, lakini lazima niondoke sasa “Thank you, but I must leave now” answers the invitation rather than trying to calculate the polarity of the negative wording. The question with huoni is potentially confrontational; it presupposes that the evidence should be visible. Use challenging negative questions cautiously with people you do not know well. This is a pragmatic difference, not a new conjugation.

Optional Je, and information questions

Je, can introduce an affirmative or negative polar question. It is useful in (formal) interviews, questionnaires, announcements, and careful writing, but ordinary (informal) conversation commonly relies on intonation alone.

Je, hujapokea uthibitisho wa malipo?

Have you not received confirmation of payment?

Je, kampuni haitafungua matawi mapya mwaka huu?

Will the company not open new branches this year?

Neutral checks in institutional settings

A negative question need not be hostile or surprised. An administrator or clinician may calmly check whether an expected item is missing or an expected condition is absent.

Je, hujapokea beji yako ya mkutano?

Have you not received your conference badge?

Huna mzio wowote wa dawa unaoujua, sawa?

You don't have any drug allergy that you know of, correct?

Answer the fact rather than merely echoing the expectation: Sina mzio wowote ninaoujua “I have no allergy that I know of,” or Nina mzio wa penisilini “I am allergic to penicillin.” A calm setting and neutral intonation make these checklist questions informational rather than accusatory.

Do not confuse a negative polar question with an information question that asks why, who, or what about a negative event. In Kwa nini hukufika?, the speaker presupposes non-arrival and asks for its cause; “yes” or “no” is not a complete answer.

Kwa nini hukufunga dirisha kabla ya mvua kuanza?

Why didn't you close the window before the rain began?

Nani hajawasilisha fomu yake bado?

Who has not submitted their form yet?

Answer the proposition, not an English tag

English responses to negative questions are famously unstable: “Yes” may mean “yes, I did” or “yes, that is correct—I did not,” depending on speaker and situation. Standard Swahili makes the intended polarity clearest by repeating the relevant predicate. A confirming ee or ndiyo can agree with the negative proposition as worded; it does not automatically reverse the verb's polarity.

Hujafika bado? — Ee, sijafika; niko njiani karibu na posta.

You haven't arrived yet? — That's right, I haven't; I'm on the way near the post office.

Hujafika bado? — Nimefika; ninakusubiri mapokezini.

You haven't arrived yet? — I have arrived; I'm waiting for you at reception.

The first answer confirms non-arrival with si-ja-fik-a. The second rejects it with positive ni-me-fik-a. A bare ndiyo, ee, or hapana can be interpreted through local conversational habits and the speaker's stance; cross-regional contact makes the possibilities even less safe for a learner. Repeating the verb is not cumbersome—it is the normal way to make the proposition explicit.

Hamtaendelea na kikao? — Ndiyo, hatutaendelea; umeme umekatika.

You won't continue with the meeting? — That's right, we won't continue; the power has gone out.

Hutaki tiketi mbili? — Nataka mbili, si moja.

You don't want two tickets? — I do want two, not one.

Hutakuja Jumatano, bali Alhamisi? — Nitakuja Alhamisi; nimebadilisha ratiba yangu.

You won't come on Wednesday, but rather on Thursday? — I'll come on Thursday; I've changed my schedule.

Here bali corrects one day in favor of another. The answer repeats the positive predicate nitakuja, so the actual arrangement stays clear even though the question begins from non-arrival on Wednesday.

Naam is a respectful or (formal) affirmative response. Ee is common (informal) confirmation. Neither word repairs an unclear predicate by itself, so retain the full clause whenever a misunderstanding would matter.

💡

With a negative question, answer in a complete Swahili clause: sijafika or nimefika, hatutaendelea or tutaendelea. This avoids importing an English rule for whether “yes” reverses or confirms the negative wording.

Negative question versus confirmation tag

The whole predicate is negative in Hutakuja kesho? “Won't you come tomorrow?” A positive statement plus a tag has a different structure: Utakuja kesho, sivyo? “You will come tomorrow, right?” Both can seek confirmation, but they do not assert the same proposition.

Hutakuja kwenye mazoezi kesho? Nilidhani ulikuwa huru.

Won't you come to practice tomorrow? I thought you were free.

Utakuja kwenye mazoezi kesho, sivyo? Tumekuwekea nafasi.

You'll come to practice tomorrow, right? We've saved you a place.

The first question foregrounds possible non-attendance. The second starts from expected attendance and requests agreement. In writing, the comma before the tag helps display that two-part structure.

Common Mistakes

Keeping affirmative present -na- under negation

❌ Hunaenda ofisini leo?

Incorrect — the second-person present negative removes -na- and changes final -a to -i.

✅ Huendi ofisini leo?

Aren't you going to the office today?

Adding a free negative word to an affirmative perfect

❌ Hapana umefika kituoni?

Incorrect — hapana is an answer or rejection, not a particle placed before unchanged umefika.

✅ Hujafika kituoni?

Haven't you arrived at the station?

Using the past negative for a perfect question

❌ Hukufika bado?

Wrong for the intended 'not yet' meaning — -ku- is completed past, while -ja- marks an event not completed up to now.

✅ Hujafika bado?

Haven't you arrived yet?

Giving a bare answer whose polarity is unclear

❌ Hujalipa? — Ndiyo.

Pragmatically unclear across contexts — the listener cannot safely tell whether payment happened.

✅ Hujalipa? — Bado sijalipa; nitalipa jioni.

You haven't paid? — I haven't paid yet; I'll pay this evening.

Key Takeaways

A negative question is a fully inflected negative predicate used interrogatively, not an affirmative verb plus a free equivalent of English not. Present, past, perfect, and future each make a different replacement inside the verb. Negative wording can signal surprise, confirmation, invitation, or challenge, so context and intonation matter. Most importantly, answer Hujafika? with the predicate that is true—sijafika or nimefika—instead of trusting a bare English-style yes/no calculation. The broader negative paradigms are mapped on the negation overview, and response strategies receive fuller treatment under yes–no responses.
