Let's Forms with tu-...-e | Swahili Grammar

English “let’s” proposes an action that includes the speaker and at least one other person. Standard Swahili normally uses the first-person plural subjunctive: tu- + optional object + verb base + appropriate final vowel, as in tu-som-e → tusome “let’s read” and tw-end-e → twende “let’s go.” The negative inserts -si- after tu-: tu-si-end-e → tusiende “let’s not go.”

These inclusive proposals are neutral in (informal) conversation and (formal) deliberation. Tone and framing can make the same form an enthusiastic invitation, a practical suggestion, or a chairperson’s proposal. The morphology says “we should/may do this”; it does not encode the speaker’s authority or the listeners’ enthusiasm.

The inclusive subjunctive build

Finished form	Complete analysis	Proposal
tusome	tu-som-e	let’s read
tuanze	tu-anz-e	let’s begin
tumsaidie	tu-m-saidi-e	let’s help him/her
tuzipitie	tu-zi-piti-e	let’s review them
twende	tw-end-e	let’s go
tule	tu-l-e	let’s eat
tusisahau	tu-si-saha-u	let’s not forget
tusimwache	tu-si-mw-ach-e	let’s not leave him/her

Regular final -a becomes subjunctive -e. Object markers remain before the root, after tu- in the affirmative and after tu-si- in the negative. The finished finite complex is one word.

Tusome ujumbe wote kabla ya kujibu kwa hasira.

Let’s read the whole message before replying angrily.

Tu-som-e proposes joint reading. It has no ordinary present -na- and does not assert that reading is already underway.

Tuzipitie hoja hizi moja baada ya nyingine ili tusikose jambo muhimu.

Let’s review these points one by one so that we do not miss anything important.

In tu-zi-piti-e, class 10 object -zi- refers to hoja hizi. Negative purpose tu-si-kos-e independently shares the first-person plural subject.

💡

Inclusive “let’s” is not a special translation particle. It is a first-person plural subjunctive, so agreement, object marking, stem shape, and polarity all remain visible inside the verb.

A proposal, not an ordinary present statement

Compare tunasoma and tusome. Present tu-na-som-a reports what “we” are doing or habitually do. Subjunctive tu-som-e puts reading forward as a desired next action.

Tunasoma sura ya pili sasa; tusome sura ya tatu baada ya mapumziko.

We are reading chapter two now; let’s read chapter three after the break.

The first clause is an assertion. The second is a proposal whose later time comes from baada ya mapumziko, not a future TAM marker.

Tunazungumzia gharama, lakini sasa tujadili ratiba ya utekelezaji.

We are discussing the cost, but now let’s discuss the implementation schedule.

Present tu-na-zungumzi-a describes the current topic. Subjunctive tu-jadili retains lexical final -i and proposes the next topic.

The same distinction works in a question:

Twende sasa au tusubiri mpaka mvua ipungue?

Shall we go now, or should we wait until the rain eases?

Both twende and tu-subiri are subjunctive. Question intonation requests agreement rather than merely ordering the group.

Regular stems, non-a verbs, and short roots

For a regular final-a verb, replace -a with -e: kuanza → tuanze, kusaidia → tusaidie. Verbs ending lexically in -i, -u, or -e retain that vowel.

Tujibu barua hii leo ili mteja asisubiri wiki nyingine.

Let’s answer this letter today so that the customer does not wait another week.

Borrowed-final jibu gives tu-jibu, not tujibe. The absence of -na- and the proposal context identify the mood.

Tusafiri alfajiri; barabara huwa haina msongamano wakati huo.

Let’s travel at dawn; the road is usually not congested then.

Tu-safiri likewise retains final -i. Do not force every inclusive proposal to end visibly in -e.

Short roots lose the support ku- found in many indicative forms:

Tule kitu kidogo kabla ya kuanza safari ya kurudi.

Let’s eat something small before starting the return journey.

Tu-l-e has short root -l-; it is not tukule. With kwenda, vowel interaction and the stored root produce tw-end-e → twende.

Twende kwa miguu; kituo kiko karibu kuliko nilivyodhani.

Let’s go on foot; the station is closer than I thought.

The standard form is twende, not a mechanical tuende copied from the infinitive’s spelling. See the forms of kwenda.

Objects and reciprocal coordination

An inclusive proposal can contain any object marker licensed by the ordinary verb template.

Tumsaidie jirani yetu kuhamisha kabati kabla giza halijaingia.

Let’s help our neighbor move the cupboard before dark.

Human object -m- occurs once in tu-m-saidi-e. The overt noun jirani yetu identifies that person.

Tuwatumie washiriki ratiba mpya kabla hawajaanza safari.

Let’s send the participants the new schedule before they begin their journey.

Plural-human object -wa- follows subject tu- in tu-wa-tumi-e. English places “the participants” after the verb, but Swahili’s bound marker keeps its inner slot.

Sometimes English “let’s” proposes allowing another person to act rather than acting together: “Let’s let Asha speak.” Swahili must express both layers.

Tumwache Asha amalize maelezo yake kabla hatujauliza maswali.

Let’s let Asha finish her explanation before we ask questions.

Inclusive tu-mw-ach-e proposes “our” act of allowing; embedded a-maliz-e assigns finishing to Asha. One tu- form cannot make Asha the actor of the second event.

Negative inclusive proposals

Use tu-si-, not ordinary first-person plural negative hatu-. The negative subjunctive proposes collective nonperformance.

Tusiende sokoni leo; mvua imeziba barabara kuu.

Let’s not go to the market today; the rain has blocked the main road.

Tu-si-end-e contrasts with hatuendi “we are not going/we do not go.” The latter reports a fact or plan; it does not have the same proposal force.

Tusimwache mtoto peke yake hata kwa dakika chache.

Let’s not leave the child alone even for a few minutes.

The order is tu-si-mw-ach-e: inclusive subject, negative mood, human object, root, final -e.

Tusisahau kuwajulisha wageni kwamba muda umebadilika.

Let’s not forget to inform the guests that the time has changed.

Lexical-final kusahau gives tu-si-sahau. The negative marker does not force -e onto a verb whose lexical final vowel is -u.

💡

To negate “let’s,” preserve inclusive tu- and insert -si-: tusome → tusisome, twende → tusiende. Ordinary hatu- produces an indicative negative, not a negative proposal.

Strength and register

Bare twende can be energetic or directive when the speaker is leading a group. A question, Twende?, requests agreement. Words such as basi “then/in that case,” labda “perhaps,” and tafadhali can shape the discourse force without entering the verb.

Labda tuanze na maswali rahisi kabla ya kujadili bajeti.

Perhaps let’s begin with the easy questions before discussing the budget.

This is appropriate in neutral and (formal) deliberation. Labda softens the proposal; subjunctive tu-anz-e still carries the inclusive grammar.

Common Mistakes

Using the present as if it meant let’s

❌ Tunasoma sehemu inayofuata sasa!

Incorrect for the intended proposal — this asserts 'we are reading' rather than proposing it.

✅ Tusome sehemu inayofuata sasa, halafu tupumzike.

Let’s read the next section now, then take a break.

Copying the infinitive spelling into twende

❌ Tuende nyumbani kabla mvua haijaanza.

Nonstandard for the intended subjunctive of kwenda — the established Standard form is twende.

✅ Twende nyumbani kabla mvua haijaanza kunyesha.

Let’s go home before it starts raining.

Using indicative negation for a negative proposal

❌ Hatuendi huko leo!

Incorrect for 'let’s not go there' — this is an indicative statement that we are not going.

✅ Tusiende huko leo mpaka tupate maelekezo zaidi.

Let’s not go there today until we receive further instructions.

Keeping final -a on a regular stem

❌ Tuanza kikao baada ya kila mtu kufika.

Incorrect — regular kuanza takes subjunctive final -e.

✅ Tuanze kikao baada ya kila mtu kufika.

Let’s begin the meeting after everyone arrives.

Moving an object marker after the verb

❌ Tusaidie mzee yeye kuvuka barabara.

Incorrect for an object-marked inclusive proposal — the human marker belongs before the stem.

✅ Tumsaidie mzee huyo kuvuka barabara yenye shughuli nyingi.

Let’s help that elderly man cross the busy road.

Key Takeaways

Inclusive proposals use first-person plural subjunctive tu-...-e or the appropriate lexical final vowel. Twende, tule, and other short-root forms do not preserve infinitival support mechanically. Object markers stay inside the fixed template. Negative “let’s not” uses tu-si-, while ordinary tuna- and hatu- make indicative assertions rather than proposals.
