Long Swahili sentences can place several nouns between a controller and a later verb or modifier. The agreement requirement does not weaken with distance: in gari la mwalimu ambaye amefika limeharibika “the car of the teacher who has arrived has broken down,” class 5 gari still controls li- on the final verb. Class 1 mwalimu controls ambaye amefika inside the intervening phrase, but it does not take over the outer clause.
The temptation to use the features of a nearby noun is called agreement attraction. In careful Standard Swahili editing, the cure is structural: find each head, mark the domain it controls, and verify its dependents outward. This page develops that diagnostic across intervening phrases, relative clauses, and coordinated modifiers. It does not replace the dedicated guides to relative-clause formation or mixed coordinated subjects.
Distance does not replace grammatical structure
A short clause makes the controller obvious: gari limeharibika. Expanding its noun phrase should not change the outer subject concord.
Gari la mwalimu limeharibika nje ya shule.
The teacher's car has broken down outside the school.
Gari la mwalimu mpya wa shule limeharibika nje ya hospitali.
The new schoolteacher's car has broken down outside the hospital.
Class 5 gari controls li-me-haribika in both. Class 1 mwalimu locally controls mpya and class 1 associative wa before shule. Neither nearby noun is the subject of limeharibika.
Three parallel long chains
The following sentences use the same architecture with three noun classes: demonstrative + coordinated adjectives + relative clause + main predicate.
Mhandisi huyu mrefu na mwema ambaye kampuni ilimwajiri mwaka jana ameongoza mradi vizuri.
This tall and kind engineer whom the company hired last year has led the project well.
Daraja hili refu na jembamba ambalo wahandisi walilikagua jana limefunguliwa tena.
This long, narrow bridge, which the engineers inspected yesterday, has reopened.
Vifaa hivi vipya na vizito ambavyo mkandarasi alivileta jana vimehifadhiwa ghalani.
This new, heavy equipment that the contractor brought yesterday has been stored in the warehouse.
Class 1 gives huyu—mrefu—mwema—ambaye—m-—a- in the first chain: object marker -m- in ilimwajiri refers to the engineer, while final a- begins ameongoza. Class 5 gives hili—refu—jembamba—ambalo—li-—li- in walilikagua and limefunguliwa. Class 8 gives hivi—vipya—vizito—ambavyo—vi-—vi- in alivileta and vimehifadhiwa.
Each relative clause also has its own overt subject: class 9 kampuni with i-, plural human wahandisi with wa-, and class 1 mkandarasi with a-. Long-distance reading succeeds when these interleaved chains are kept separate.
Relative markers and embedded verb marking have different jobs
In an amba- relative, the final relative element agrees with the head being modified: ambaye class 1, ambalo class 5, ambavyo class 8, ambazo class 10. The finite verb inside the relative clause separately agrees with its own subject. If the head is represented as the embedded object, an object marker can repeat its class on the embedded verb.
Ripoti hizi ambazo kamati ya wataalamu ilizikagua jana zimechapishwa leo.
These reports, which the committee of specialists checked yesterday, were published today.
There are three class 10 links to outer ripoti: ambazo, embedded object -zi- in ilizikagua, and main subject zi- in zimechapishwa. Inside the relative clause, class 9 kamati controls subject i- in ilizikagua. The plural class 2 noun wataalamu is closest to that verb, but it sits inside the associative phrase ya wataalamu and is not its subject.
Pendekezo ambalo viongozi wa wilaya walilijadili kwa saa mbili limekubaliwa.
The proposal that the district leaders discussed for two hours has been accepted.
Class 5 pendekezo controls ambalo, -li- in walilijadili, and final li- in limekubaliwa. Class 2 viongozi controls embedded wa- in walilijadili as well as associative wa before wilaya. Class 9 wilaya is the complement of that associative phrase and controls no marker in this sentence.
For the mechanics of the two relative strategies, see agreement across relative clauses. The editing principle here is broader: every marker has a controller even when several chains cross the same stretch of words.
Coordinated modifiers repeat the head's agreement
When two true adjectives jointly modify one noun, each independently selects the same controller's adjective concord. The conjunction na does not make the second adjective agree with the nearest noun or become invariable.
Vyumba hivi vikubwa na vyeupe vilivyo mwishoni mwa ukumbi vitatumiwa kwa mkutano.
These large, white rooms at the end of the hall will be used for the meeting.
Class 8 controls hivi, vikubwa, vyeupe, vilivyo, and vi-ta-tumiwa. The intervening locative phrase mwishoni mwa ukumbi has its own local mwa, but it cannot attract the future subject marker.
Miti hii mirefu na myembamba iliyo kando ya barabara itaondolewa kesho.
These tall, slender trees beside the road will be removed tomorrow.
Class 4 controls hii, mirefu, myembamba, iliyo, and i-ta-ondolewa. The singular class 9 noun barabara occurs closer to the main verb, yet class 4 remains the outer controller.
Do not confuse coordinated modifiers with coordinated noun heads. Viti vikubwa na vizuri has one class 8 controller and two adjectives. Kiti na meza vimevunjika coordinates two heads and requires a resolution strategy, a genuinely variable topic treated elsewhere.
An editing diagnostic that scales
For a sentence with several possible attractors, use four passes:
- Bracket the head phrase. Find the noun that determines the outer syntactic role, not merely the last noun before the verb.
- List its targets. Include demonstratives, adjectives, possessives, relative markers, resumptive object markers when present, and the outer subject marker.
- Bracket embedded clauses and phrases. Identify their local subjects and objects separately.
- Read each chain outward. Confirm every target against its controller's concord series; do not “repair” an invariable word.
Apply this to the next sentence:
Sanduku hili kubwa la vifaa ambavyo wauguzi waliviagiza mwezi uliopita limewasili leo.
This large box of equipment that the nurses ordered last month arrived today.
The outer class 5 chain is sanduku—hili—kubwa—la—li- in limewasili. Inside the associative phrase, class 8 vifaa controls ambavyo and object -vi- in waliviagiza. Class 2 wauguzi controls embedded subject wa- in waliviagiza. None of those three chains should be flattened into one.
This method is particularly useful in (formal) reports and (academic) prose, where long postnominal phrases are common. In (informal) conversation, speakers often split a dense sentence into two clauses; that is a stylistic choice, not a suspension of agreement.
Agreement attraction versus genuine alternatives
Not every unexpected agreement form is an accidental attraction error. Coordinated noun phrases from different classes permit resolution strategies that vary across speakers, and human nouns can trigger semantic class 1/2 agreement. Those constructions need their own analysis.
By contrast, a single unambiguous head separated from its predicate by an associative phrase or relative clause does not acquire the nearest noun's class in edited Standard Swahili. Gari la walimu limefika has one class 5 subject; wamefika would say that the teachers arrived, changing the structure and meaning.
Gari la walimu limefika, lakini walimu wenyewe bado hawajafika.
The teachers' car has arrived, but the teachers themselves have not arrived yet.
The contrast makes the controllers explicit: gari—li- in the first clause, walimu—hawa- in hawajafika in the second.
Common Mistakes
Agreeing the outer verb with the nearest possessor
❌ Gari la walimu wamefika.
Incorrect for 'the teachers' car has arrived' — plural human walimu is inside the possessor phrase, not the outer subject.
✅ Gari la walimu limefika.
The teachers' car has arrived.
Letting an embedded subject control the main verb
❌ Daraja ambalo wahandisi walilikagua wamefunguliwa.
Incorrect — wahandisi controls only the embedded verb; class 5 daraja controls the main verb.
✅ Daraja ambalo wahandisi walilikagua limefunguliwa.
The bridge that the engineers inspected has been opened.
Marking only the first coordinated adjective
❌ Vifaa hivi vipya na zito vimehifadhiwa ghalani.
Incorrect — both true adjectives agree independently with class 8 vifaa.
✅ Vifaa hivi vipya na vizito vimehifadhiwa ghalani.
This new, heavy equipment has been stored in the warehouse.
Repairing only the final verb in a corrupted chain
❌ Vitabu hii mpya ya shule ambayo mwalimu alipendekeza imefika.
Incorrect — all the dependent forms follow a singular class 9 pattern instead of plural class 8 vitabu.
✅ Vitabu hivi vipya vya shule ambavyo mwalimu alivipendekeza vimefika.
These new school books that the teacher recommended have arrived.
The correction changes hii → hivi, mpya → vipya, ya → vya, ambayo → ambavyo, adds class 8 object -vi- in alivipendekeza, and changes main subject i- → vi-. The embedded class 1 subject mwalimu keeps a- because it belongs to a different chain. That is the controller-outward diagnostic in its fullest form.
Key Takeaways
Agreement depends on grammatical control, not linear distance. Intervening possessors, relative-clause subjects, and nouns inside prepositional phrases may create attraction, but they do not replace a clear outer head. Coordinated modifiers each agree directly with that head, while embedded clauses maintain their own local chains. Bracket the structure, identify controllers, and audit every dependent outward.
