Swahili has absorbed vocabulary through centuries of contact, especially from Arabic and, more recently, English. A borrowed noun does not remain grammatically foreign: speakers assign it to a Swahili noun class, give it an established plural pattern, and make surrounding words agree with it. Kompyuta may resemble English “computer,” but its plural is not kompyutas; number appears in kompyuta hizi zime-.
There is no universal “loanword class.” Many nonhuman loans use the same visible form in classes 9/10, others take class 5/6 plural ma-, and human loans trigger human concord even when their noun prefixes are atypical. The borrowed-noun assignment page gives the wider class diagnostics. Unless variation is specifically noted, the examples below represent current Standard Swahili in both (informal) and (formal) use.
Same-form loans in classes 9/10
A large group of established loans has no visible singular–plural change. Arabic-origin barua “letter,” kalamu “pen,” and safari “journey,” and English-origin kompyuta “computer,” benki “bank,” and hoteli “hotel” commonly follow class 9 in the singular and class 10 in the plural.
Kompyuta hii mpya imefika, lakini kompyuta hizi tatu bado hazijaunganishwa.
This new computer has arrived, but these three computers have not yet been connected.
Kalamu ile imekauka, kwa hiyo nimeleta kalamu hizi mbili za ziada.
That pen has dried out, so I brought these two spare pens.
The nouns themselves are unchanged. Singular hii, ime- contrasts with plural hizi, hazija-; mbili also carries plural class 10 concord. Number belongs to the whole phrase and clause rather than to one ending on the noun.
Hoteli hii iko karibu na bahari, lakini hoteli zile ziko katikati ya mji.
This hotel is near the sea, but those hotels are in the city center.
Tumepanga safari ndefu moja, si safari fupi nyingi.
We have planned one long journey, not many short journeys.
The second example contrasts class 9 moja with class 10 nyingi. English articles and plural -s do not supply either distinction in Swahili.
Established ma- plurals
Other loans have entered the class 5/6 pattern, with a usually unprefixed singular and plural ma-. Common human examples include daktari/madaktari “doctor(s),” dereva/madereva “driver(s),” rais/marais “president(s),” and rubani/marubani “pilot(s).” Gari/magari “car(s)” is a frequent nonhuman example.
Gari hili la kukodi limeharibika, lakini magari yale mawili yanafanya kazi vizuri.
This rental car has broken down, but those two cars work well.
Daktari huyu amemwona mgonjwa, na madaktari hawa watajadili matokeo baadaye.
This doctor has seen the patient, and these doctors will discuss the results later.
The noun pair daktari/madaktari has class 5/6 morphology, but human reference selects huyu/hawa and a-/wa- rather than nonhuman hili/haya and li-/ya-. This semantic human concord is systematic in Standard Swahili; it is not permission to change the noun plural to an invented wadaktari.
Dereva mpya amesubiri nje, na madereva wengine wameingia ofisini.
The new driver waited outside, and the other drivers entered the office.
Marubani wawili wamekagua ndege kabla ya safari.
Two pilots inspected the aircraft before the flight.
Human agreement spreads across wawili and wame-. The visible plural ma- on marubani and class 2 agreement on its dependents therefore coexist.
Arabic loans are not one grammatical type
Arabic has contributed many everyday Swahili words, but origin does not predict class. Compare class 9/10 habari “news/report(s)” and safari “journey(s),” whose noun form can remain unchanged; class 5/6 swali/maswali “question(s)” and jibu/majibu “answer(s)”; and human rafiki/marafiki “friend(s).” Each has become part of Swahili's own lexicon.
Swali hili ni gumu, lakini maswali yale yamejibiwa kwa ufupi.
This question is difficult, but those questions were answered briefly.
Jibu moja halitoshi; tunahitaji majibu matatu yenye ushahidi.
One answer is not enough; we need three answers supported by evidence.
Do not infer a plural merely from the source language. Modern speakers learn swali/maswali and jibu/majibu as Swahili pairs. Historical knowledge may explain the vocabulary, but present-day agreement determines how it behaves.
English loans enter existing class patterns
Newer technology terms frequently enter classes 9/10 with an unchanged noun: intaneti, video, blogu, and programu. The English form app is widespread in bilingual (informal) use, but careful Standard Swahili normally prefers programu tumizi. Established spelling, register, and class behavior matter more than reproducing English morphology.
Video hii imepakiwa leo, na video zile zimeondolewa kwa sababu ya makosa.
This video was uploaded today, and those videos were removed because of errors.
Programu mpya imeboresha huduma, lakini programu mbili za zamani zimefungwa.
The new program improved the service, but two old programs were shut down.
Some occupational loans instead develop a ma- plural and human concord, as with meneja/mameneja “manager(s).” The exact outcome is conventional. When a new borrowing has real variation, consult current edited usage or a reliable dictionary rather than applying a personal plural rule.
Competing strategies are lexical, not freely interchangeable
Borrowing creates pressure among several Swahili patterns. A same-form class 9/10 plural is common, and ma- is productive with many loans, but an individual established noun normally has a preferred pattern. For instance, Standard Swahili uses kompyuta for both numbers and madaktari as the plural of daktari.
Nimenunua kompyuta mbili kwa maabara na kuwaajiri madaktari wawili kwa kliniki.
I bought two computers for the laboratory and hired two doctors for the clinic.
The object nouns display different plural strategies in one sentence. Kompyuta stays unchanged and receives class 10 mbili; madaktari shows ma- and, because it denotes people, receives human wawili and object marker -wa- in kuwaajiri.
Reference without articles
Borrowed nouns do not import English a/an/the. A bare noun can be new, familiar, generic, or specific; context and modifiers refine the reading.
Nahitaji hoteli karibu na kituo, lakini hoteli hiyo isiwe ghali sana.
I need a hotel near the station, but that hotel must not be too expensive.
The first bare hoteli introduces an indefinite requirement. The demonstrative hiyo then identifies the relevant hotel. Swahili builds reference through discourse and concord rather than a mandatory article slot.
Common Mistakes
Adding English plural -s
❌ Kompyutas hizi zimewekwa maktabani.
Incorrect — kompyuta has the same noun form in singular and plural.
✅ Kompyuta hizi zimewekwa maktabani.
These computers have been placed in the library.
Adding ma- to every borrowed noun
❌ Makalamu haya yameanguka mezani.
Incorrect — the standard plural of kalamu is kalamu with class 10 agreement.
✅ Kalamu hizi zimeanguka mezani.
These pens fell onto the table.
Omitting an established ma- plural
❌ Daktari hawa wameanza zamu ya usiku.
Incorrect — the plural noun is madaktari, although its agreement is human.
✅ Madaktari hawa wameanza zamu ya usiku.
These doctors have started the night shift.
Using nonhuman concord for a person
❌ Dereva hili limefika mapema leo.
Incorrect — dereva denotes a person and takes human concord.
✅ Dereva huyu amefika mapema leo.
This driver arrived early today.
Inserting an English article
❌ Ninatafuta a hoteli yenye chumba kimoja.
Incorrect — English a does not occupy a Swahili article slot.
✅ Ninatafuta hoteli yenye chumba kimoja.
I am looking for a hotel with one room.
Key Takeaways
- Loans enter Swahili noun classes; they do not bring English or Arabic plural grammar with them.
