Quantified phrases can contain several nouns, but proximity does not decide agreement. In chupa mbili za maji zimebaki “two bottles of water remain,” the nearby class 6 noun maji does not control the verb. The grammatical head chupa is plural class 10, so its chain is mbili—za—zi-.
This page gives a practical test for counts, containers, measures, and partitives. The patterns are neutral in (informal) and (formal) Standard Swahili. First identify what the phrase is counting or treating as a portion; then build every concord from the resulting controller.
Direct counts: the counted noun remains the head
A numeral normally modifies the noun being counted. It does not become the controller itself. Numerals one through five show class agreement, while higher numerals are generally invariable; either way, demonstratives, adjectives, and verbs still take their concord from the counted noun.
The full numeral paradigms are collected on Numerals in the Noun Phrase; here the important question is which noun controls the surrounding chain.
Watoto watatu wadogo wamebaki darasani.
Three young children have remained in the classroom.
Magari mawili mapya yamewasili asubuhi hii.
Two new cars arrived this morning.
Vikombe vitano vikubwa vimewekwa mezani.
Five large cups have been placed on the table.
The parallel chains are class 2 wa-tatu—wa-dogo—wa-, class 6 ma-wili—ma-pya—ya-, and class 8 vi-tano—vi-kubwa—vi-. The spelling in an ordinary sentence has no analytic hyphens: write watatu, mawili, and vitano.
Containers: the container controls
In a container phrase, the outer noun names the units being counted. The contents follow in an associative phrase with “of.” The container controls its numeral, modifiers, associative -a form, and the main verb.
Chupa hizi mbili kubwa za maji zimebaki mezani.
These two large bottles of water remain on the table.
Vikombe hivi viwili vipya vya chai vimepasuka.
These two new cups of tea have cracked.
Gunia hili moja kubwa la mchele limefika dukani.
This one large sack of rice has arrived at the shop.
In the first sentence, class 10 chupa gives hizi, mbili, kubwa, za, and zi-. Class 6 maji supplies the meaning of the contents but no concord outside its own phrase. In the second, class 8 vikombe gives hivi, viwili, vipya, vya, and vi-; class 9 chai is again only the complement. In the third, class 5 gunia controls hili, moja, kubwa, la, and li-.
This distinction can change the truth of a sentence. Chupa mbili zimebaki says two containers remain; it does not say how much water remains inside them.
Measure nouns behave like heads
Units such as lita, kilo, and mita are nouns. When several units are counted, the plural measure is commonly treated as class 10 and controls the agreement chain, while the measured substance follows after class 10 associative za.
Lita mbili za maziwa zimetosha kwa watoto wote.
Two liters of milk have been enough for all the children.
Kilo tano za unga zimewasili leo.
Five kilograms of flour arrived today.
The English verb may be singular in “two liters is enough,” but Standard Swahili follows the plural measure units: lita mbili ... zimetosha. The class 6 complement maziwa cannot attract ya- across za.
For an amount viewed as one package rather than several units, speakers can choose a singular head such as kiasi “amount”:
Kiasi hiki cha maziwa kimetosha kwa watoto wote.
This amount of milk has been enough for all the children.
Now class 7 kiasi controls hiki, cha, and ki-. The real-world quantity can be identical; the grammatical packaging has changed.
Lexical part nouns: nusu and sehemu control
Words that name a portion can be ordinary lexical heads. Sehemu “part” and nusu “half” are commonly class 9 singular in this head-controlled construction, so they take i- even when their complements belong to another class.
See sehemu, kiasi and Measure Quantifiers for their wider meanings and placement.
Sehemu kubwa ya chakula imebaki kwa ajili ya kesho.
A large part of the food remains for tomorrow.
Nusu ya maziwa imebaki kwenye jagi.
Half of the milk remains in the jug.
In sehemu kubwa ya chakula imebaki, class 9 sehemu controls adjective kubwa, associative ya, and verb i-. The class 7 complement chakula does not trigger ki-. Likewise, class 6 maziwa does not trigger ya- when class 9 nusu is the head.
With a countable complement, especially a human plural, speakers also use complement-controlled agreement when the sentence is about the selected members rather than the fraction as one amount:
Nusu ya wanafunzi wamefika tayari.
Half of the students have already arrived.
Here class 2 wanafunzi supplies wa-; compare the amount reading in nusu ya maziwa imebaki. In (formal) writing, choose the controller that matches the intended construal and keep it consistent. An overt lexical head favors head agreement, while a member-focused partitive favors the complement.
Transparent partitives: baadhi ya lets the complement control
The quantifier baadhi ya “some of” behaves differently from lexical sehemu and nusu. It does not supply the noun-class controller for the rest of the clause. The noun after ya supplies agreement according to its own class.
Baadhi ya wanafunzi hawa wamechelewa kwa sababu ya mvua.
Some of these students are late because of the rain.
Baadhi ya miti hii imeanguka baada ya dhoruba.
Some of these trees have fallen after the storm.
Baadhi ya vitabu hivi vimepotea maktabani.
Some of these books have gone missing in the library.
The complement controllers create three distinct chains: class 2 wanafunzi—hawa—wa-, class 4 miti—hii—i-, and class 8 vitabu—hivi—vi-. The fixed-looking ya in baadhi ya is not evidence for class 9 control.
Agreeing pronominal quantifiers make the complement class even more visible: wengi wa wanafunzi wamefika “many of the students have arrived,” mingi ya miti imeanguka “many of the trees have fallen,” and vingi vya vitabu vimepotea “many of the books have gone missing.” These forms are useful when selecting members from a known set, but their internal paradigms are covered on the dedicated quantifier pages.
A controller-first decision test
Use this sequence before choosing any marker:
- If a numeral directly counts a noun, that counted noun controls.
- If a container or unit is named, the container or measure noun controls.
- If a lexical portion noun such as sehemu or nusu is construed as the head amount, that portion noun controls; in a member-focused partitive, the countable complement can control instead.
- If the construction is transparent baadhi ya, the quantified complement controls.
Then regenerate demonstrative, numeral, adjective, associative concord, and verb separately. This controller-outward method catches errors that a nearest-noun strategy misses.
Common Mistakes
Letting the contents control a container phrase
❌ Chupa mbili za maji yamebaki mezani.
Incorrect — maji is nearby, but plural class 10 chupa is the head.
✅ Chupa mbili za maji zimebaki mezani.
Two bottles of water remain on the table.
Making a plural measure singular because English allows it
❌ Lita mbili za maziwa imetosha.
Incorrect — plural class 10 lita requires zi-.
✅ Lita mbili za maziwa zimetosha.
Two liters of milk have been enough.
Giving baadhi class 9 control
❌ Baadhi ya vitabu hivi imepotea.
Incorrect — the class 8 complement vitabu controls the predicate.
✅ Baadhi ya vitabu hivi vimepotea.
Some of these books have gone missing.
Repairing only the nearest marker
❌ Chupa haya mawili makubwa ya maji yamebaki.
Incorrect — the entire chain has been attracted to class 6 maji.
✅ Chupa hizi mbili kubwa za maji zimebaki.
These two large bottles of water remain.
The full correction changes demonstrative haya → hizi, numeral mawili → mbili, adjective makubwa → kubwa, associative ya → za, and subject marker ya- → zi-. Every repaired marker points back to class 10 chupa.
Key Takeaways
- Direct counts agree with the counted noun, not with the numeral itself.
- Containers and measure units control agreement over their contents.
- Lexical part nouns such as sehemu and nusu can control their own class.
- Transparent baadhi ya leaves the quantified complement in control.
- Diagnose the head first, then verify every concord in the chain independently.
