English has a morphological participle paradigm: writing/written, breaking/broken. Those forms help build progressives and perfects, modify nouns, and reduce subordinate clauses. Standard Swahili distributes these functions across finite verbs, noun-class relative forms, -ki- clauses, passives, statives, and lexical nominal or adjectival expressions. There is no invariant Swahili suffix that learners can label “the present participle” or “the past participle.”
This absence is not a gap in expressive power. Swahili often encodes more information than an English participle because subject class, relative agreement, TAM, voice, and event viewpoint appear in the verb complex.
Six participial functions, six Swahili builds
| English phrase | Swahili strategy | Analytic build |
|---|---|---|
| the crying child | mtoto anayelia | a-na-ye-li-a |
| people waiting outside | watu wanaosubiri nje | wa-na-o-subiri |
| the letter written yesterday | barua iliyoandikwa jana | i-li-yo-andik-w-a |
| the food that was cooked | chakula kilichopikwa | ki-li-cho-pik-w-a |
| she entered laughing | aliingia akicheka | a-li-ingi-a + a-ki-chek-a |
| the door is closed | mlango umefungwa | u-me-fung-w-a |
The relative markers -ye-, -o-, -yo-, and -cho- agree with different noun classes. Passive -w- derives the affected-subject verb. Analytic hyphens expose these choices but disappear in ordinary spelling.
Mtoto anayelia amepoteza kiatu chake.
The crying child has lost one of his shoes.
Class 1 relative a-na-ye-li-a is a full agreeing verb, not an invariant adjective meaning “crying.”
Barua iliyoandikwa jana ina makosa mawili katika anwani.
The letter written yesterday has two errors in the address.
Class 9 barua controls past relative passive i-li-yo-andik-w-a. English hides subject agreement in “written”; Swahili displays class, past viewpoint, relative linkage, and passive voice.
Present-participle modifiers become relative verbs
An English present participle can compress “who/that is doing.” Swahili normally restores the relative relationship.
Wateja wanaosubiri nje wataruhusiwa kuingia baada ya saa moja.
The customers waiting outside will be allowed to enter after seven.
Plural-human wateja selects wa-na-o-subiri. Main future passive wa-ta-ruhusi-w-a is separate.
Gari linalozuia lango halina dereva ndani.
The car blocking the gate has no driver inside.
Class 5 gari selects li-na-lo-zui-a. An English learner who inserts a bare kuzuia after gari loses both the relative link and noun-class agreement.
Tumesikia sauti inayotoka kwenye chumba cha injini.
We have heard a sound coming from the engine room.
Class 9 sauti controls i-na-yo-tok-a. Present relative -na- is appropriate because the source event is current at the reference point.
Not every English -ing modifier is eventive. “A charming person” may require a lexical adjective, relative property clause, or idiom according to meaning. Morphology cannot replace lexical judgment.
Past-participle modifiers combine relative TAM and voice
English past participles often describe an affected entity. Swahili usually uses a passive relative whose subject agrees with that entity.
Nyaraka zilizotumwa jana zimefika katika ofisi zote.
The documents sent yesterday have reached all the offices.
Class 10 nyaraka selects zi-li-zo-tum-w-a. The sender can be added with na: nyaraka zilizotumwa na katibu “documents sent by the secretary.”
Daraja lililoharibiwa na mafuriko limefungwa kwa muda.
The bridge damaged by the floods has been closed temporarily.
Class 5 past relative passive is li-li-lo-harib-iw-a. Main perfect passive li-me-fung-w-a reports the current closure.
Chakula kilichobaki kitawekwa kwenye friji.
The food left over will be put in the refrigerator.
Here ki-li-cho-bak-i uses intransitive kubaki “remain,” not a passive translation of English “left.” This is why learners must analyze meaning rather than attach passive -w- to every English -ed form.
Reduced adverbial participles become full -ki- clauses
English reduces clauses such as “walking home” or “being tired.” Swahili -ki- forms retain subject concord.
Asha alirudi nyumbani akibeba mifuko miwili mizito.
Asha returned home carrying two heavy bags.
Wakiwa wamechoka, wachezaji waliomba mapumziko mafupi.
Being tired, the players asked for a short break.
The first has past anchor a-li-rudi and simultaneous a-ki-beb-a. The second uses situational wa-ki-w-a plus perfect/state wa-me-chok-a. English participles omit the repeated subject; Swahili repeats plural-human agreement.
Nilimwona mlinzi akifungua lango la nyuma.
I saw the guard opening the back gate.
The guard is the object of ni-li-mw-on-a but subject of a-ki-fungu-a. The -ki- clause is dependent, yet it is not “nonfinite” in the English sense of having no subject marking.
Compound tenses do not need participles
English builds “was reading” and “had written” with an auxiliary plus participle. Swahili uses a finite form of kuwa followed by another inflected verb.
Tulipofika, katibu alikuwa akiandika muhtasari wa kikao.
When we arrived, the secretary was writing the meeting summary.
Mkutano ulipoanza, katibu alikuwa ameandika kurasa mbili tayari.
When the meeting began, the secretary had already written two pages.
The second words a-ki-andik-a and a-me-andik-a have their own subject and aspect marking. They are not invariant present and past participles. See kuwa as an auxiliary.
Result states, adjectives, and lexical nouns
A passive perfect can present a current result: mlango umefungwa “the door has been closed/is closed.” A stative extension may instead express a resulting property or possibility: mlango umefungika “the door has become closed/can close,” depending on context. A lexical adjective or predicate may be better for a conventional property: mlango uko wazi “the door is open.”
Duka limefungwa leo, lakini litafunguliwa kesho asubuhi.
The shop is closed today, but it will be opened tomorrow morning.
Ripoti iko tayari, lakini nakala iliyosainiwa bado haijafika.
The report is ready, but the signed copy has not arrived yet.
Tayari is a lexical predicate; i-li-yo-saini-w-a is a past relative passive. English adjectives and participles do not determine the Swahili category by themselves.
For conventional concepts, a deverbal noun may replace an English participle-derived noun: uongozi “leadership,” uandishi “writing/authorship,” ufundishaji “teaching methodology.” These have their own noun classes and cannot be derived by a universal participial ending.
Register and stylistic choice
Full relatives are neutral in (informal) and (formal) Standard Swahili. Dense sequences of passive relatives are especially common in (formal) administrative and (academic) prose, but excessive literal copying from English can sound heavy. Natural Swahili may choose an active relative, a lexical noun, or two finite clauses when that better identifies participants.
Common Mistakes
Placing a bare infinitive after a noun
❌ Abiria kusubiri nje wataitwa sasa.
Incorrect for “passengers waiting outside” — the modifier needs relative agreement.
✅ Abiria wanaosubiri nje wataitwa sasa.
The passengers waiting outside will be called now.
Inventing an invariant -ing suffix
❌ Mtoto lia-ing amepotea.
Incorrect — Swahili uses an agreeing relative verb.
✅ Mtoto anayelia anahitaji msaada.
The crying child needs help.
Omitting class concord from a past relative
❌ Barua aliandikwa jana imefika.
Incorrect — barua needs class 9 relative i-li-yo-, not human a-.
✅ Barua iliyoandikwa jana imefika.
The letter written yesterday has arrived.
Making every English -ed modifier passive
❌ Chakula kilichobakiwa kitawekwa kwenye friji.
Incorrect for “food left over” — kubaki is intransitive here, not passive.
✅ Chakula kilichobaki kitagawanywa kesho.
The food left over will be distributed tomorrow.
Key Takeaways
- Swahili has no invariant present/past participle pair corresponding to English -ing/-ed.
- Noun-modifying events normally use relative verbs with noun-class concord, TAM, and voice.
- Simultaneous reduced clauses use subject-marked -ki- forms.
- Compound tenses combine finite kuwa with another inflected verb, not a participle.
- Passive results, stative meanings, lexical predicates, and deverbal nouns must be chosen by meaning rather than English word shape.

- How Swahili Translates English -ing FormsB1 — Choose among a class-15 infinitive, a finite -na- verb, a situational -ki- clause, a relative clause, and a lexical noun for English -ing forms.
