Comparatives with zaidi ya | Swahili Grammar

Swahili uses zaidi to place an amount, action, or quality higher on a scale. Depending on what follows, it can mean “more,” “further,” or “to a greater degree.” It does not behave like English comparative -er: the adjective keeps its ordinary noun-class agreement, while zaidi and the comparative expression zaidi ya remain unchanged.

The most useful distinction is between degree and a standard. In gari kubwa zaidi, zaidi raises the degree of size: “a larger car.” In zaidi ya magari matatu, zaidi ya introduces a threshold: “more than three cars.” When two things are compared for a quality, kuliko is often the clearest word introducing the second term: gari kubwa zaidi kuliko lile “a larger car than that one.” All unlabelled patterns on this page are neutral in current Standard Swahili.

Zaidi follows the expression whose degree it raises

With a true adjective, zaidi normally follows the agreeing adjective. The noun-class prefix belongs to the adjective, not to zaidi.

Tunatafuta chumba kikubwa zaidi kwa ajili ya mikutano.

We are looking for a larger room for meetings.

Asha amechagua vikapu vidogo zaidi ili vitoshee kwenye rafu.

Asha has chosen smaller baskets so that they will fit on the shelf.

Class 7 chumba selects kikubwa; class 8 vikapu selects vidogo. English changes big to bigger and small to smaller. Swahili first builds a well-formed description—chumba kikubwa, vikapu vidogo—and then adds invariant zaidi.

The same placement works with invariable property words. These words describe a property but do not take adjective concord.

Hoteli ya karibu ni ghali zaidi wakati wa sikukuu.

The nearby hotel is more expensive during the holidays.

Njia hii ni rahisi zaidi ukisafiri na watoto.

This route is easier if you are travelling with children.

Do not create ighali for class 9 hoteli or irahisi for class 9 njia. Ghali and rahisi are lexically invariable, so the correct comparative forms are ghali zaidi and rahisi zaidi. By contrast, -kubwa and -dogo are true adjective stems and must agree. The guide to what counts as an adjective explains why English “adjective” corresponds to several Swahili structures.

💡

Remove zaidi and check the remaining phrase. If chumba kikubwa is correct by itself, chumba kikubwa zaidi will preserve that agreement. Comparative marking never repairs a faulty adjective form.

Zaidi ya sets a threshold or introduces what is exceeded

The sequence zaidi ya is especially natural before a number, measure, quantity, or other threshold. Here ya is part of the fixed comparative expression; it does not change to la, cha, or vya to match the preceding noun.

Mkutano ulidumu zaidi ya saa tatu bila mapumziko.

The meeting lasted more than three hours without a break.

Zaidi ya wakazi mia mbili walihudhuria mkutano wa kijiji.

More than two hundred residents attended the village meeting.

Gharama imeongezeka kwa zaidi ya asilimia kumi mwaka huu.

The cost has risen by more than ten percent this year.

In each example, the phrase after ya supplies the point being exceeded. No noun-class controller changes the form of ya. This use is close to English “more than,” but its position is flexible because the entire zaidi ya phrase can quantify a subject, object, duration, or amount.

Zaidi ya can also introduce another participant as the standard of an action or degree. In a simple quality comparison, however, many speakers prefer kuliko because it unambiguously means “than.”

Rehema anasoma zaidi ya ndugu yake wakati wa mitihani.

Rehema studies more than her sibling during exam time.

This can naturally compare how much they study. If the intended comparison is specifically between two descriptions, kuliko makes the structure more transparent: Rehema ana bidii zaidi kuliko ndugu yake “Rehema is more diligent than her sibling.” The separate comparison with kuliko page develops that linker in full.

Zaidi and kuliko can work together

In description + zaidi + kuliko + standard, zaidi marks increased degree and kuliko introduces the comparison standard. This combination is common and clear.

Daraja jipya ni refu zaidi kuliko lile la zamani.

The new bridge is longer than the old one.

Matokeo ya mwaka huu ni mazuri zaidi kuliko tulivyotarajia.

This year's results are better than we expected.

The class 5 subject daraja controls jipya and refu. The class 6 subject matokeo controls mazuri. Neither zaidi nor kuliko agrees. A comparison can often omit zaidi—daraja ni refu kuliko lile is already “the bridge is longer than that one”—but adding it makes the scalar meaning explicit or gives “even/more” emphasis in context.

With verbs, zaidi measures the frequency, duration, effort, or extent of the action rather than an adjective’s degree.

Tangu ahamie karibu, Musa anatembea zaidi kuliko anavyoendesha gari.

Since moving nearby, Musa walks more than he drives.

Tunahitaji kusikiliza zaidi kuliko kuzungumza katika mkutano huu.

We need to listen more than speak in this meeting.

The finite forms anatembea and tunahitaji remain single written words. Zaidi is an independent adverb following the verb or the larger predicate it modifies.

Swahili offers several routes to a comparable property

Swahili’s inventory of true adjective stems is smaller than English’s, but the language has productive alternatives. Each one places zaidi differently according to its internal grammar.

Strategy	Base description	Comparative
agreeing adjective	ofisi kubwa	ofisi kubwa zaidi
-enye property phrase	ofisi yenye nafasi	ofisi yenye nafasi zaidi
associative -a phrase	huduma ya haraka	huduma ya haraka zaidi
property verb	ofisi inafaa	ofisi inafaa zaidi

Tutachagua ukumbi wenye nafasi zaidi kuliko huu.

We will choose a hall with more space than this one.

Here class 3 ukumbi selects wenye, but the noun nafasi is the quantity increased by zaidi. It would be wrong to invent a direct adjective meaning “spacious” merely because English has one.

Wateja wanataka huduma ya haraka zaidi kuliko tuliyokuwa tukitoa awali.

Customers want faster service than what we used to provide before.

The associative connector is class 9 ya because it modifies huduma. The comparative does not turn haraka into an agreeing adjective. A property verb supplies yet another natural option:

Mpango huu unafaa zaidi kwa familia zenye watoto wadogo.

This plan is more suitable for families with young children.

English speakers often search for one Swahili adjective corresponding to spacious, fast, or suitable. That search misses the central system: true adjectives, -enye phrases, associative phrases, and verbs package different meanings. The small adjective class is therefore a gateway to more precise choices, not a defect in the language.

💡

Ask what is being increased. In yenye nafasi zaidi, it is the amount of space; in huduma ya haraka zaidi, it is the degree of speed; in inafaa zaidi, it is the suitability expressed by the verb.

Context can leave the standard unspoken

If the alternatives are already known, zaidi need not be followed by ya or kuliko. The listener recovers the comparison set from the situation.

Kati ya njia hizi mbili, napenda ile fupi zaidi.

Of these two routes, I prefer the shorter one.

Class 9 njia is understood after ile, and N-class fupi has its ordinary form. The opening phrase supplies the two-route comparison set. Without such context, fupi zaidi simply means “shorter” or “more short,” not automatically “the shortest of every possible route.” Superlative readings are treated on the superlatives page.

Common Mistakes

Copying the English comparative suffix

❌ Tunahitaji chumba kikubwaer kwa mkutano.

Incorrect — Swahili does not attach English -er to an adjective.

✅ Tunahitaji chumba kikubwa zaidi kwa mkutano.

We need a larger room for the meeting.

Leaving a true adjective without agreement

❌ Vikapu hivi ni kidogo zaidi kuliko vile.

Incorrect — class 8 vikapu requires vidogo.

✅ Vikapu hivi ni vidogo zaidi kuliko vile.

These baskets are smaller than those.

Making the fixed ya agree

❌ Mkutano ulidumu zaidi cha saa tatu.

Incorrect — zaidi ya is fixed; cha is not selected by saa.

✅ Mkutano ulidumu zaidi ya saa tatu.

The meeting lasted more than three hours.

Inventing an adjective where Swahili uses -enye

❌ Tunahitaji ukumbi mnafasi zaidi.

Incorrect — there is no regular adjective stem -nafasi meaning spacious.

✅ Tunahitaji ukumbi wenye nafasi zaidi.

We need a hall with more space.

Key Takeaways

Use zaidi after a quality or action to mean “to a greater degree,” and use zaidi ya before a threshold or quantity meaning “more than.” For a clearly expressed standard in a quality comparison, zaidi kuliko is common and transparent. Keep ordinary concord on true adjectives, -enye, associative -a, and verbs; zaidi, fixed comparative ya, and kuliko do not acquire noun-class prefixes.
