Kuja means “come”: move toward the speaker, listener, home base, or another reference point chosen in the conversation. Its lexical root is the single syllable -ja, so positive forms such as anakuja, alikuja, and atakuja retain ku- to provide enough phonological weight. Negative and subjunctive forms behave differently.
The positive imperative is irregular njoo, with plural njooni. These forms, together with the short negative siji and subjunctive aje, make kuja one of the high-frequency verbs that should be learned as a compact paradigm rather than guessed from the English translation.
Complete practical paradigm
| Form | I | you (sg.) | he/she | we | you (pl.) | they |
|---|---|---|---|---|---|---|
| present | ninakuja | unakuja | anakuja | tunakuja | mnakuja | wanakuja |
| past | nilikuja | ulikuja | alikuja | tulikuja | mlikuja | walikuja |
| perfect | nimekuja | umekuja | amekuja | tumekuja | mmekuja | wamekuja |
| future | nitakuja | utakuja | atakuja | tutakuja | mtakuja | watakuja |
| present negative | siji | huji | haji | hatuji | hamji | hawaji |
| past negative | sikuja | hukuja | hakuja | hatukuja | hamkuja | hawakuja |
| subjunctive | nije | uje | aje | tuje | mje | waje |
Affirmative a-na-ku-ja gives anakuja. Present negative drops both present -na- and the supportive ku-, then changes final -a to -i: ha-ji “he/she is not coming.” Past negative ha-ku-ja also surfaces as hakuja, but here -ku- is the negative-past marker, not retained infinitive ku-.
Ninakuja sasa; nisubiri karibu na lango kuu.
I'm coming now; wait for me near the main gate.
Wageni hawakuja jana kwa sababu ndege yao ilifutwa.
The guests did not come yesterday because their flight was canceled.
Natumaini atakuja mapema ili tuanze kwa wakati.
I hope she will come early so that we start on time.
Imperative njoo and njooni
Use njoo for one addressee and njooni for more than one.
Njoo hapa unisaidie kufungua dirisha hili.
Come here and help me open this window.
Njooni kwetu Jumamosi tule chakula cha mchana pamoja.
Come to our place on Saturday so that we can have lunch together.
The long vowel in njoo is written twice. Njo and ja are not Standard imperatives. Negative commands use subjunctive forms usije and msije.
Msije bila kutupigia simu, kwa sababu huenda tusiwe nyumbani.
Do not come without calling us, because we may not be home.
In other contexts usije... can introduce a warning meaning “lest you...,” but as a complete motion command it straightforwardly means “do not come.”
Choosing kuja by viewpoint
The physical route does not decide between kuja and kwenda by itself. Kuja points toward a conversational center; kwenda points away from it.
Utakuja ofisini kesho, au tutazungumza kwa simu?
Will you come to the office tomorrow, or shall we talk by phone?
The speaker treats the office as the relevant meeting point, even if not currently there. Likewise, a host says Njoo kwangu “Come to my place,” while the guest may tell a third person Ninaenda kwake “I am going to his/her place.”
Tutakuja kwako baada ya kumaliza kazi mjini.
We will come to your place after finishing our work in town.
Asha alikuja kutoka Tanga jana usiku.
Asha came from Tanga last night.
Source is introduced with kutoka; destination may be hapa, nyumbani, kwetu, or another locative phrase. Kuja kwa Amina normally means come to Amina’s place or to Amina.
Come and do something
A following infinitive commonly states why someone comes.
This is one of the central linked-infinitive patterns: the motion verb is finite and the purpose verb keeps infinitive ku-.
Nimekuja kukusaidia kuhamisha makabati.
I have come to help you move the cupboards.
The build is ni-me-ku-ja ku-ku-saidi-a: nimekuja is finite, while kukusaidia is a separate infinitive with second-person object marker -ku-.
Fundi atakuja kukagua mashine kesho asubuhi.
The technician will come to inspect the machine tomorrow morning.
With an invitation or joint action, an imperative plus subjunctive is especially natural:
Njoo tuzungumze nje ambako kuna utulivu.
Come, let's talk outside where it is quiet.
Tu-zungumz-e does not mean that “come” takes an object. It presents the intended joint action after arrival.
Coming with someone or bringing something
Kuja na means “come with” and can imply bringing something along, but ordinary “bring” as a transitive instruction is kuleta.
Alikuja na watoto wake wawili kwenye sherehe.
She came to the celebration with her two children.
Ukija kesho, leta mkataba uliosainiwa.
When you come tomorrow, bring the signed contract.
The first sentence profiles shared motion; the second profiles transfer of the contract. Do not force an object marker into kuja to mean “bring it.”
Register and common formulas
The paradigm is neutral across (informal) and (formal) Standard Swahili. Karibu is the conventional invitation “welcome/come in,” while njoo is a direct command and can sound abrupt without context. Add tafadhali or use a subjunctive request for politeness: Tafadhali uje mapema. In (formal) invitations, Tafadhali fika... “Please arrive...” may specify attendance more neutrally.
Common Mistakes
Dropping ku in an affirmative tense
❌ Wageni wanaja saa kumi jioni.
Incorrect ordinary present form — short -ja retains ku-.
✅ Wageni wanakuja saa kumi jioni.
The guests are coming at four in the afternoon.
Keeping ku in the present negative
❌ Yeye hakujii leo.
Incorrect present negative for kuja; this also resembles an extended stem.
✅ Yeye haji leo.
She is not coming today.
Guessing the imperative from the root
❌ Ja hapa haraka.
Incorrect Standard imperative.
✅ Njoo hapa haraka.
Come here quickly.
Choosing kwenda from the traveler's viewpoint only
⚠️ Utakwenda kwangu kesho?
Grammatical from another viewpoint, but not the usual choice when inviting the listener toward the speaker's place.
✅ Utakuja kwangu kesho?
Will you come to my place tomorrow?
Key Takeaways
- Positive indicative forms retain ku- before the monosyllabic root -ja.
- Present negative drops it: siji, huji, haji, hatuji, hamji, hawaji.
- The imperative is irregular njoo/njooni; subjunctive forms are nije, uje, aje, tuje, mje, waje.
- Choose kuja for motion toward the conversation’s reference point, not simply by the traveler’s physical direction.
- Use a following infinitive for purpose and kuleta when “bring” is genuinely transitive.
