kulala — to Sleep, Lie Down | Swahili Grammar

Kulala means “sleep,” “lie down,” and in some contexts “spend the night.” Although lala looks like the syllable la repeated, its modern basic stem is lal-a, built on root -lal-, not like short kula “eat.” It therefore forms ninalala and nililala without retaining infinitive ku-.

The sleeper is subject; location and duration follow outside the verb. Causatives lalisha and laza add someone who causes or enables the posture/sleep, but they have partly distinct conventional uses and should not be reduced to one mechanical suffix rule.

Complete practical paradigm

Form	I	you (sg.)	he/she	we	you (pl.)	they
present	ninalala	unalala	analala	tunalala	mnalala	wanalala
past	nililala	ulilala	alilala	tulilala	mlilala	walilala
perfect	nimelala	umelala	amelala	tumelala	mmelala	wamelala
future	nitalala	utalala	atalala	tutalala	mtalala	watalala
present negative	silali	hulali	halali	hatulali	hamlali	hawalali
past negative	sikulala	hukulala	hakulala	hatukulala	hamkulala	hawakulala
subjunctive	nilale	ulale	alale	tulale	mlale	walale

The builds are ni-na-lal-a → ninalala, si-lal-i → silali, and ni-lal-e → nilale. Imperatives are lala/laleni; prohibitions are usilale/msilale.

Ninalala mapema ninapokuwa na kazi nyingi asubuhi.

I go to bed early when I have a lot of work in the morning.

Watoto hawakulala vizuri kwa sababu ya kelele za sherehe.

The children did not sleep well because of the party noise.

Tulale sasa ili tuamke kabla ya jua kuchomoza.

Let us sleep now so that we wake before sunrise.

💡

Do not confuse kulala with short kula. Kulala drops infinitive ku- in ordinary affirmative tenses: ninalala, not ninakulala.

This contrast is explained structurally on the short-root page: apparent visual shortness does not determine whether infinitive ku- survives inside a finite verb. The basic stem of kulala is lal-a, so its tense forms are entirely regular.

Sleep, fall asleep, and be asleep

Context and TAM shape the English translation.

Mtoto amelala, kwa hiyo zima televisheni.

The child is asleep, so turn off the television.

Perfect a-me-lal-a presents the current state resulting from lying down/falling asleep. English naturally uses “is asleep,” not always “has slept.”

Nililala mara tu baada ya kuweka simu pembeni.

I fell asleep as soon as I put the phone aside.

Simple past plus mara tu favors the transition into sleep. With a duration, it reports the whole sleeping interval:

Jana nililala kwa saa saba bila kuamka.

Yesterday I slept for seven hours without waking up.

Common combinations include lala fofofo “sleep very soundly,” lala salama “sleep well/safely,” and lala usingizi “sleep.” Kulala usingizi is possible, but ordinary kulala needs no cognate object.

Location and spending the night

Wageni wamelala katika chumba cha nyuma.

The guests are sleeping in the back room.

Tutalala kwa shangazi tukifika mjini usiku.

We will spend the night at our aunt's place if we reach town at night.

Use locatives such as kitandani, chumbani, and sakafuni. With a person, kwa shangazi/rafiki refers to that person’s home or hospitality.

Usilale sakafuni bila mkeka; kuna baridi sana.

Do not sleep on the floor without a mat; it is very cold.

These patterns are neutral in (informal) and (formal) Standard Swahili. In accommodation contexts, kulala can mean lodge/spend the night without specifying actual sleep.

Causative lalisha

Kulalisha (lal-ish-a) adds a causer or host and commonly means make/put someone to sleep or accommodate someone overnight.

Mama alimlalisha mtoto baada ya kumsomea hadithi.

The mother put the child to sleep after reading him a story.

A-li-m-lal-ish-a has mother as causer and child as human object indexed by -m-.

Familia hiyo ilitulalisha sebuleni wakati vyumba vilipojaa.

That family accommodated us in the living room when the bedrooms were full.

Here i-li-tu-lal-ish-a means provide us a place to sleep. It is not necessarily coercive.

Laza and the posture/result meaning

Kulaza is an established shorter causative and strongly favors putting or laying someone/something down; in medical contexts kulazwa means be admitted to hospital.

Muuguzi alimlaza mgonjwa ubavuni kabla ya kumchunguza.

The nurse laid the patient on his side before examining him.

Mzee alilazwa hospitalini kwa uchunguzi zaidi.

The older man was admitted to hospital for further examination.

The boundaries overlap: both lalisha and laza can be translated “put to sleep/bed.” Lalisha transparently relates to the sleep/accommodation event; laza is frequent for bodily placement and the lexical medical sense. Actual collocation, not a universal direct-versus-indirect rule, decides.

Both causatives can be passivized, but the lexical distinction remains. Kulalishwa focuses on someone being made or enabled to sleep, whereas kulazwa often describes placement or hospital admission. These are established members of the wider causative system, not freely interchangeable forms predicted only from the suffix.

Watoto walilalishwa mapema kwa sababu safari ingeanza alfajiri.

The children were put to bed early because the journey would begin at dawn.

💡

Learn both causatives: lalisha for causing/providing sleep, laza for laying down and common medical lazwa. Do not assume one is merely a tense form of the other.

Common Mistakes

Treating kulala as a short verb

❌ Jana nilikulala mapema.

Incorrect — kulala does not retain infinitive ku- after past -li-.

✅ Jana nililala mapema.

Yesterday I went to sleep early.

Keeping final -a in the present negative

❌ Silala vizuri mchana.

Incorrect present negative — final -a changes to -i.

✅ Silali vizuri mchana.

I do not sleep well during the day.

Giving intransitive lala an object

❌ Mama alimlala mtoto baada ya chakula.

Incorrect — causing the child to sleep needs a causative stem.

✅ Mama alimlalisha mtoto baada ya chakula.

The mother put the child to sleep after the meal.

Confusing sleep with bodily placement

❌ Mfanyakazi alimlalisha sanduku ubavuni.

Wrong lexical choice for simply laying an object on its side.

✅ Mfanyakazi alilaza sanduku ubavuni.

The worker laid the box on its side.

Key Takeaways

Kulala behaves as an ordinary full stem despite its repeated-looking syllables.
Perfect amelala commonly describes the current state “is asleep.”
Locations use locative nouns or kwa + person for spending the night at someone’s place.
Lalisha causes/provides sleep; laza favors laying down and medical admission.
