Bila means “without.” It can introduce a noun—chai bila sukari “tea without sugar”—or a class 15 infinitive—aliondoka bila kusema “she left without speaking.” In both patterns, bila supplies the negative relation; the noun or infinitive itself stays formally affirmative.
With an infinitive, the unexpressed actor is normally the subject of the main clause. Juma aliondoka bila kulipa means that Juma both left and failed to pay. If another actor is intended, name that actor before the infinitive or use a finite clause that can mark its person, tense, and polarity explicitly.
Bila plus a noun
After bila, a noun phrase names an absent object, resource, condition, or accompaniment. There is no article and no separate word corresponding to English “not.”
| With/present relation | Without relation | Meaning |
|---|---|---|
| chai yenye sukari | chai bila sukari | tea with sugar / without sugar |
| kuingia kwa ruhusa | kuingia bila ruhusa | enter with permission / without permission |
| ripoti yenye sahihi | ripoti bila sahihi | a report with / without a signature |
| safari yenye matatizo | safari bila matatizo | a journey with / without problems |
Nipe kahawa bila sukari, lakini ongeza maziwa kidogo.
Give me coffee without sugar, but add a little milk.
Mgeni hawezi kuingia katika jengo hili bila kitambulisho halali.
A visitor cannot enter this building without valid identification.
Walituma rasimu bila sahihi ili tuisome kabla ya kuidhinisha.
They sent an unsigned draft so that we could read it before approving it.
The phrase can modify a noun (kahawa bila sukari) or complete a verb (kuingia bila kitambulisho). Its internal form does not agree with the head noun: bila remains invariant.
Bila plus a ku-infinitive
To express “without doing,” place the ordinary affirmative infinitive after bila. The main finite verb carries subject and time; the infinitive names the action that did not accompany it.
| Accompanied event | Event without accompaniment | Structural change |
|---|---|---|
| Alisaini baada ya kusoma. | Alisaini bila kusoma. | baada ya replaced by bila; infinitive unchanged |
| Aliingia huku akibisha. | Aliingia bila kubisha. | bila denies accompanying knocking |
| Waliondoka baada ya kuaga. | Waliondoka bila kuaga. | main past remains; infinitive unchanged |
Dereva alianza safari bila kuangalia kiwango cha mafuta.
The driver began the journey without checking the fuel level.
The build is a-li-anz-a + bila + ku-angali-a. Only alianza carries third-person subject and past -li-.
Tulipokea kifurushi bila kupewa taarifa ya kwamba kilikuwa kimefika.
We received the package without being notified that it had arrived.
Passive infinitive ku-pe-w-a retains ordinary passive morphology. Bila does not change its slots.
Asha alijibu maswali yote bila kutumia kamusi.
Asha answered all the questions without using a dictionary.
English selects an -ing form after “without.” Swahili does not create a special gerund ending; it uses the same class 15 ku- form found in many nonfinite complements.
The default is one shared subject
When no actor appears inside the bila phrase, listeners normally assign the infinitive to the main-clause subject.
Musa alipita karibu nasi bila kutusalimia.
Musa passed near us without greeting us.
Musa is both the passer and the nongreeter. The infinitive contains first-person plural object -tu- in ku-tu-salimi-a, but no separate subject marker.
Watoto walikula matunda bila kuyaosha kwanza.
The children ate the fruit without washing them first.
Plural-human watoto controls past wa-li-kul-a and is also understood as the actor of ku-ya-osh-a. Class 6 object marker -ya- refers to matunda.
Usitume ujumbe huo bila kuusoma tena kwa makini.
Do not send that message without reading it again carefully.
Here the addressee is understood as the actor of both negative subjunctive u-si-tum-e and infinitive ku-u-som-a. Main-clause negation does not change the form after bila.
Naming a different actor
An overt noun phrase or independent pronoun can precede the infinitive. It is the logical subject of that nonfinite clause, even though the infinitive still has no finite subject prefix.
Meneja alibadilisha saa ya mkutano bila sisi kujua.
The manager changed the meeting time without us knowing.
The manager performed alibadilisha; independent sisi identifies the knowers in sisi kujua. Without sisi, the sentence would normally suggest that the manager changed it unknowingly.
Ripoti ilichapishwa bila mhariri kuikagua katika toleo lake la mwisho.
The report was published without the editor reviewing it in its final version.
The subject of kuikagua is mhariri. Class 9 object marker -i- refers to ripoti: ku-i-kagu-a → kuikagua.
Waliondoka mapema bila watoto wao kuamka.
They left early without their children waking up.
This overt-subject pattern is neutral in careful Standard Swahili. It is especially valuable when both possible actors are human and context cannot disambiguate them.
When a finite alternative is clearer
The ordinary infinitive after bila cannot independently express finite tense, person agreement, or perfect aspect. Swahili can negate an infinitive with kuto-, but placing that form after bila nests one negative expression inside another: bila kutofanya means roughly “without failing to do,” not simple “without doing.” When the subordinate situation needs its own tense, actor agreement, or straightforward finite polarity, use a finite clause rather than forcing those distinctions into bila + infinitive.
Mkurugenzi alisaini mkataba wakati wakili hakuwa ameukagua bado.
The director signed the contract when the lawyer had not yet reviewed it.
Finite hakuwa ameukagua identifies the lawyer, marks a prior unfinished review, and anchors it relative to the signing. Bila wakili kuupitia would simply present the missing review, without that independent tense structure.
Amina aliondoka, na sisi hatukujua kwamba alikuwa amepata kazi nyingine.
Amina left, and we did not know that she had found another job.
The coordinate finite clause avoids any doubt about who knew what and when. This is often clearer than piling several complements after bila sisi kujua in (formal) prose.
Bila versus kuto-
Both constructions concern nonoccurrence, but they organize the sentence differently. Kuto- makes a negative event itself into a complement or nominal topic. Bila relates an absent accompaniment to a main event that did occur.
Kutotoa risiti ni ukiukaji wa kanuni za duka.
Not issuing a receipt is a violation of the shop's rules.
Muuzaji alichukua malipo bila kutoa risiti.
The seller took payment without issuing a receipt.
The first is about the practice of non-issuance; the second reports a payment event lacking an accompanying receipt event. The negative-infinitive guide develops the kuto- word.
Do not combine the two mechanically. Bila kutofanya literally places “not doing” inside the scope of “without” and tends toward “without failing to do,” not simple “without doing.” It is logically possible in a carefully constructed contrast but needlessly difficult in ordinary communication.
Main-clause negation and scope
Negating the finite verb does not merely intensify bila. It denies the combined event.
Abiria hakuondoka kwenye teksi bila kulipa nauli.
The passenger did not leave the taxi without paying the fare.
Ordinarily, this implies that the passenger paid before leaving, or possibly that the passenger did not leave. It does not mean Abiria aliondoka bila kulipa nauli “The passenger left without paying.” Each negative operator has its own scope.
Register and alternatives
Bila is neutral in (informal) conversation and (formal) writing. Pasipo is a more elevated alternative meaning “without” in many contexts and is common in (formal) or (literary) prose, but bila remains the safest everyday choice. Fixed bila shaka “without doubt/certainly” is neutral to (formal) and expresses confidence rather than a negative proposition.
Bila shaka tutahitaji muda zaidi kukamilisha ukaguzi huu.
Without doubt, we will need more time to complete this inspection.
Common Mistakes
Adding a negative predicate after bila
❌ Aliingia ofisini bila hakutoa kitambulisho.
Incorrect — bila takes a noun or infinitive here, not a finite negative verb.
✅ Aliingia ofisini bila kutoa kitambulisho kwa mlinzi wa langoni.
He entered the office without showing identification to the guard at the entrance.
Copying an English -ing form
❌ Alimaliza hotuba bila sema-ing neno kuhusu bajeti.
Incorrect — Swahili uses a ku-infinitive after bila.
✅ Alimaliza hotuba bila kusema neno lolote kuhusu bajeti mpya.
She finished the speech without saying anything about the new budget.
Hiding a different subject
❌ Juma aliuza nyumba bila kujua.
Wrong for ‘without his children knowing’ — this normally makes Juma the one who did not know.
✅ Juma aliuza nyumba bila watoto wake kujua kuhusu mpango huo.
Juma sold the house without his children knowing about the plan.
Negating the infinitive redundantly
❌ Waliondoka bila kutolipa bili ya hoteli.
Wrong for simple ‘without paying’ — kuto- reverses the event already placed under bila.
✅ Waliondoka bila kulipa bili ya hoteli iliyokuwa mezani.
They left without paying the hotel bill that was on the table.
Giving the infinitive finite subject marking
❌ Tulifika bila tulipoteza mzigo wowote njiani.
Incorrect — a same-subject complement after bila is infinitival, not past finite.
✅ Tulifika bila kupoteza mzigo wowote njiani licha ya mvua.
We arrived without losing any luggage on the way despite the rain.
Key Takeaways
- Bila + noun expresses an absent thing or condition; bila + ku-infinitive means “without doing.”
- The infinitive stays affirmative in form because bila supplies the negative relation.
- Without an overt embedded actor, the main-clause subject normally controls the infinitive.
- Put another actor before the infinitive, or use a finite clause when that actor needs independent tense or polarity.
- Kuto- nominalizes a negative event; bila relates a missing accompaniment to a main event.
