yuko, iko, ziko and Other Locative Copular Forms | Swahili Grammar

To say where a known person or thing is, Standard Swahili uses an agreeing locative copula: Amina yuko ofisini “Amina is in the office,” kitabu kiko mezani “the book is on the table,” funguo ziko mfukoni “the keys are in the pocket.” English repeats is/are; Swahili changes the beginning according to the located subject.

The most broadly used series ends in -ko. Related -po presents a specific position or presence, and -mo foregrounds being inside something. This page concentrates on choosing the subject concord and building present positive and negative forms; the precise spatial contrast is developed on the next page.

The personal -ko paradigm

The positive forms combine personal subject concord with -ko. Class 1 third person uses special yu-, not ordinary verbal a-.

Person	Positive	Negative	Meaning
I	niko	siko	I am / am not at a place
you (sg.)	uko	huko	you are / are not at a place
he/she	yuko	hayuko	he/she is / is not at a place
we	tuko	hatuko	we are / are not at a place
you (pl.)	mko	hamko	you all are / are not at a place
they	wako	hawako	they are / are not at a place

The analytic builds are ni-ko, u-ko, yu-ko, tu-ko, m-ko, and wa-ko. Negative forms replace the positive subject edge: si-ko, hu-ko, hayu-ko, hatu-ko, ham-ko, and hawa-ko. Finished forms contain no hyphens.

Niko kwenye foleni ya benki; nitakupigia nikimaliza.

I am in the bank queue; I will call you when I finish.

Uko wapi sasa? Dereva anakusubiri karibu na lango la pili.

Where are you now? The driver is waiting for you near the second gate.

Mkurugenzi hayuko ofisini leo; anahudhuria mkutano mjini.

The director is not in the office today; she is attending a meeting in town.

Tuko kituoni tayari kuondoka, lakini wageni wawili bado hawako hapa.

We are at the station ready to leave, but two guests are still not here.

💡

For a third-person human location, memorize yuko–hayuko. Ordinary finite verbs use a-/ha-, but this locative copula inserts yu- in both the positive and negative series.

Noun-class forms with -ko

Nonhuman subjects select their usual class concord. The located noun—not the place phrase—controls the form.

Class	Typical subject	Positive	Negative
1	mtoto	yuko	hayuko
2	watoto	wako	hawako
3	mfuko	uko	hauko
4	mifuko	iko	haiko
5	gari	liko	haliko
6	magari	yako	hayako
7	kitabu	kiko	hakiko
8	vitabu	viko	haviko
9	barua	iko	haiko
10	barua	ziko	haziko
11/14	ufunguo / ujasiri	uko	hauko
15	kusoma	kuko	hakuko

Gari la wageni liko nyuma ya jengo, karibu na geti dogo.

The visitors' car is behind the building, near the small gate.

Vitabu vya hesabu viko kwenye rafu ya juu, lakini kamusi haiko hapo.

The mathematics books are on the top shelf, but the dictionary is not there.

Nyaraka zako ziko ndani ya bahasha ya bluu niliyoweka mezani.

Your documents are inside the blue envelope that I put on the table.

In the last two examples, plural class 8 vitabu gives vi-ko, singular class 9 kamusi gives i-ko, and plural class 10 nyaraka gives zi-ko. A physical location such as kwenye rafu never changes those controller relationships.

💡

Ask “what is being located?” In magari yako uwanjani, class 6 magari selects ya-ko. The coincidental word yako can also be a possessive meaning “your,” but syntax and the following location disambiguate it.

The place phrase does not control agreement

After the copula, Swahili can name a place in several ways: a noun with locative -ni (ofisini, shuleni), a phrase with kwenye, a spatial relator such as mbele ya, or a place name such as Dodoma. These phrases locate the subject but do not supply the concord. Compare class 5 gari liko and class 10 funguo ziko even when both are at the same garage.

Gari liko gerejini, lakini funguo zake ziko mbele ya kompyuta yangu.

The car is in the garage, but its keys are in front of my computer.

Wazazi wako Dodoma wiki hii, na mtoto wao yuko kwa shangazi yake.

The parents are in Dodoma this week, and their child is at his aunt's place.

There is therefore no single Swahili equivalent of English at or in hidden in yuko. The copula carries agreement and a broad locative perspective; the following phrase supplies the actual landmark. See the locatives overview for the forms of those place phrases.

-po and -mo use the same subject concords

Changing the locative ending changes the spatial viewpoint, not the identity of the subject. Compare the three series with the same participants.

Subject	Specific/present -po	General -ko	Interior -mo
I	nipo	niko	nimo
you (sg.)	upo	uko	umo
he/she	yupo	yuko	yumo
we	tupo	tuko	tumo
you (pl.)	mpo	mko	mmo
they	wapo	wako	wamo

Nipo hapa karibu na dirisha; unaweza kuniona ukigeuka.

I am right here near the window; you can see me if you turn around.

Asha yumo ndani ya gari akisubiri mvua ipungue.

Asha is inside the car, waiting for the rain to ease.

Vikombe vipo pale mezani, na vijiko vimo ndani ya droo.

The cups are over there on the table, and the spoons are inside the drawer.

Class 8 vikombe gives vi-po; class 8 vijiko gives vi-mo. Modern speakers often generalize -ko, so vikombe viko pale and vijiko viko ndani ya droo are also common. That variation does not make the agreeing beginning optional.

Negative -po, -ko, and -mo

Negation stays fused to the locative copula. It is not separate copular si plus a positive form.

Positive	Negative	Structural change
yupo	hayupo	class 1 yu- replaced by negative hayu-
yuko	hayuko	same subject change, general location retained
yumo	hayumo	same subject change, interior retained
vipo	havipo	class 8 vi- replaced by havi-
ziko	haziko	class 10 zi- replaced by hazi-
limo	halimo	class 5 li- replaced by hali-

Simu yangu haiko mezani; huenda niliiacha jikoni.

My phone is not on the table; perhaps I left it in the kitchen.

Watoto hawamo darasani; wako uwanjani kwa kipindi cha michezo.

The children are not inside the classroom; they are on the field for sports period.

Forms such as si yuko or si ziko are not Standard present location negation. Separate si belongs to identity or constituent contrast; location uses hayuko, haziko, and their peers.

Known location versus existence

Locative copulas place an identified discourse subject. Existential kuna introduces or asserts the presence of an entity.

Kuna mwalimu mpya mapokezini; mwalimu huyo yuko hapa kwa mahojiano.

There is a new teacher at reception; that teacher is here for an interview.

The first clause presents mwalimu mpya. The second treats mwalimu huyo as known and locates that person with yuko. English “there is” and “is here” preserve this difference, but English-speaking learners often overextend either kuna or ni.

One English be, five Swahili choices

Relation	Positive	Negative	Swahili device
identity	Amina ni mkaguzi.	Amina si mkaguzi.	invariable ni/si
property	Chumba ni kikubwa.	Chumba si kikubwa.	property predication
location	Amina yuko ghorofani.	Amina hayuko ghorofani.	agreeing locative copula
possession	Amina ana kadi.	Amina hana kadi.	agreeing -na
existence	Kuna mkaguzi nje.	Hakuna mkaguzi nje.	class 17 existential

The kuna guide handles existence; this page answers “where is the person or thing?” Past and future location normally use finite kuwa, as in alikuwa ofisini and atakuwa ofisini, rather than attaching tense to present yuko. Those paradigms belong to past and future copulas.

Register and variation

The forms are neutral Standard Swahili. Careful descriptions can maintain -po/-ko/-mo, while widespread (informal) and modern neutral usage favors -ko across many locations. The first-person and class agreement remains obligatory in either style: niko hapa may generalize -ko, but iko hapa cannot mean “I am here.”

Common Mistakes

Using ordinary class 1 a- with a locative ending

❌ Asha ako katika chumba cha mikutano.

Incorrect — class 1 uses special yu- in the positive locative copula.

✅ Asha yuko katika chumba cha mikutano akizungumza na wageni.

Asha is in the meeting room speaking with the visitors.

Using ni for a known subject's location

❌ Funguo za gari ni mfukoni mwa koti langu.

Incorrect — class 10 funguo requires an agreeing locative copula.

✅ Funguo za gari ziko mfukoni mwa koti langu la mvua.

The car keys are in the pocket of my raincoat.

Copying singular agreement onto a plural noun

❌ Vitabu vya watoto kiko chini ya kitanda.

Incorrect — class 8 vitabu requires viko.

✅ Vitabu vya watoto viko chini ya kitanda katika chumba cha wageni.

The children's books are under the bed in the guest room.

Negating with separate si

❌ Juma si yuko dukani leo asubuhi.

Incorrect — negative human location is the fused form hayuko.

✅ Juma hayuko dukani leo asubuhi kwa sababu anaumwa.

Juma is not at the shop this morning because he is ill.

Using kuna to locate a known item

❌ Simu yangu kuna kwenye chaja karibu na dirisha.

Incorrect — the identified phone is a subject, not an existential pivot.

✅ Simu yangu iko kwenye chaja karibu na dirisha la sebuleni.

My phone is on the charger near the living-room window.

Key Takeaways

Present location fuses subject concord with -po, -ko, or -mo.
Human class 1 uses yupo/yuko/yumo and negatives hayupo/hayuko/hayumo.
Nonhuman forms agree with the located noun: liko, kiko, viko, ziko and their negatives.
Use these forms to locate a known subject; use kuna to present existence.
Modern speech often generalizes -ko, but never abandons subject or noun-class agreement.
