English usually describes feelings and bodily states with be + adjective: “I am hungry,” “she is tired,” “we are cold.” Standard Swahili distributes those meanings across several grammatical frames. Hunger and thirst are things one is “with” (nina njaa, nina kiu), a specific sensation can be “felt” (ninasikia baridi), overall wellbeing uses reflexive kujisikia, pain uses kuumwa or a body-part subject, and many resulting states use a perfect verb such as nimechoka “I am tired.”
There is no single translation shortcut. The natural collocation must be learned with its construction. Unless labelled otherwise, the expressions here are neutral in both (informal) and (formal) Standard Swahili.
Kuwa na: “be with” hunger, thirst, and states
In the present, kuwa na has compact personal forms. The state noun follows them:
| Person | Positive | Negative | Example state |
|---|---|---|---|
| I | nina | sina | nina njaa |
| you (sg.) | una | huna | una kiu |
| he/she | ana | hana | ana usingizi |
| we | tuna | hatuna | tuna wasiwasi |
| you (pl.) | mna | hamna | mna haraka |
| they | wana | hawana | wana hofu |
Nina njaa sana; tule kitu kabla ya kuendelea na safari.
I am very hungry; let’s eat something before continuing the journey.
Mtoto ana usingizi, lakini hataki kuacha kucheza.
The child is sleepy, but does not want to stop playing.
English changes from “have anxiety” to “be hungry” and “be sleepy.” Swahili keeps the possessive-style frame. The complete paradigm appears under kuwa na possession.
Outside the simple present, full kuwa returns and na is separate:
Tulikuwa na kiu sana tulipofika kwenye kituo cha mwisho.
We were very thirsty when we reached the last stop.
Sijawa na hamu ya kula tangu jana jioni.
I have not had an appetite since yesterday evening.
Present sina hamu states the current lack directly; perfect negative sijawa na hamu frames a state continuing across the stated period.
Kusikia and kujisikia: a sensation versus overall condition
Basic kusikia can introduce a particular bodily sensation, especially with a noun:
Ninasikia baridi; unaweza kufunga dirisha lililo karibu nawe?
I feel cold; can you close the window near you?
Baada ya mazoezi marefu, wachezaji walisikia kiu na maumivu ya misuli.
After the long training session, the players felt thirsty and had muscle pain.
The experiencer is the subject of sikia. For overall condition, reflexive kujisikia is normally clearer:
Leo najisikia vizuri zaidi, ingawa bado nina kikohozi kidogo.
I feel better today, although I still have a slight cough.
The fuller build ni-na-ji-siki-a produces ninajisikia: subject ni-, present -na-, reflexive object -ji-, and the verb. Everyday najisikia is a common reduced surface form of that present. Compare ninasikia vizuri, which readily means “I hear well,” with najisikia vizuri, “I feel well.” This difference is not optional when context does not rescue the meaning. See kusikia for hearing and perception.
The reflexive changes with the experiencer only in the subject slot; -ji- remains constant:
| Subject | Present | Past | Present negative |
|---|---|---|---|
| I | najisikia | nilijisikia | sijisikii |
| you (sg.) | unajisikia | ulijisikia | hujisikii |
| he/she | anajisikia | alijisikia | hajisikii |
| we | tunajisikia | tulijisikia | hatujisikii |
| they | wanajisikia | walijisikia | hawajisikii |
Present negative ends in -ii: si-ji-siki-i. Both written *i*s are required.
Kuumwa and body-part subjects
Ninaumwa can mean “I am ill” or “I am in pain.” Add a body part to locate everyday pain, or make the body part the subject and mark the experiencer as object.
Ninaumwa kichwa tangu asubuhi, kwa hiyo sitatazama skrini kwa muda.
I have had a headache since morning, so I will not look at a screen for a while.
Tumbo linaniuma kila ninapokula chakula hicho.
My stomach hurts every time I eat that food.
The second build is tumbo li-na-ni-um-a: class 5 body-part subject li-, present -na-, first-person object -ni-, root um-. English puts the person in a possessive phrase (“my stomach”), while Swahili can index that experiencer inside the verb. With plural class 6 macho, agreement changes:
Macho yanamuuma baada ya kufanya kazi kwenye kompyuta usiku kucha.
His eyes hurt after working on the computer all night.
Here ya-na-mu-um-a has class 6 subject ya- and human object -mu-. In a clinic, nina maumivu ya tumbo “I have abdominal pain” is a more explicit (formal) / clinical alternative; everyday conversation often prefers tumbo linaniuma or ninaumwa tumbo.
Result-state verbs: current English adjectives, Swahili events
Several common states are expressed as results of entering that state. Perfect -me- is therefore natural:
| Swahili state | Natural English | Underlying viewpoint |
|---|---|---|
| nimechoka | I am tired | I have become tired |
| nimeshiba | I am full | I have eaten to satisfaction |
| nimefurahi | I am happy/glad | I have become pleased |
| nimekasirika | I am angry | I have become angry |
| nimelewa | I am drunk | I have become intoxicated |
Nimechoka baada ya kuendesha gari siku nzima; tuendelee kesho.
I am tired after driving all day; let’s continue tomorrow.
Tumefurahi kusikia kwamba mama ameruhusiwa kurudi nyumbani.
We are glad to hear that mother has been allowed to return home.
Replacing these with ni + adjective can change the meaning or sound unnatural. Mimi ni mchovu can characterize someone as habitually or inherently tiring/tired-looking depending on context; nimechoka reports the present result of fatigue.
A realistic clinic exchange
A: Unajisikiaje leo? B: Ninaumwa tumbo na sina hamu ya kula. A: Maumivu yalianza lini? B: Yalianza jana usiku, lakini leo yamezidi.
A: How do you feel today? B: My stomach hurts and I have no appetite. A: When did the pain start? B: It started last night, but today it has become worse.
The question uses reflexive unajisikiaje for overall condition. The patient answers with pain ninaumwa tumbo and negative possession sina hamu. Once maumivu is the discourse subject, class 6 ya- appears in yalianza, yamezidi.

Common Mistakes
Using ni with hunger
❌ Mimi ni njaa baada ya safari.
Incorrect — njaa is a state possessed with kuwa na, not an identity after ni.
✅ Nina njaa baada ya safari; hebu tutafute mahali pa kula.
I am hungry after the journey; let’s find somewhere to eat.
Using basic kusikia for overall wellbeing
❌ Ninasikia vizuri baada ya kutumia dawa.
Misleading — this most readily says that the speaker hears well.
✅ Najisikia vizuri baada ya kutumia dawa asubuhi hii.
I feel well after taking the medicine this morning.
Giving a body part human subject agreement
❌ Tumbo ananiuma nikinywa maziwa.
Incorrect — class 5 tumbo requires li-.
✅ Tumbo linaniuma nikinywa maziwa, kwa hiyo nimeacha kuyanywa.
My stomach hurts when I drink milk, so I have stopped drinking it.
Translating tired with a bare copula
❌ Leo mimi ni choka sana.
Incorrect — choka is a verb and the current result is normally perfect.
✅ Leo nimechoka sana kwa sababu sikulala vizuri usiku.
Today I am very tired because I did not sleep well last night.
Key Takeaways
- Use compact kuwa na for njaa, kiu, usingizi, hofu, and many other state nouns.
- Kusikia + noun expresses a particular sensation; reflexive kujisikia expresses overall condition.
- Kuumwa can describe illness or pain; a body part can instead control noun-class subject agreement and take the experiencer as an object marker.
- Perfect result verbs such as nimechoka, nimeshiba, and nimefurahi often translate English present adjectives.
- Natural Swahili depends on the whole collocation, not on copying English “be” or “have.”
