Karibu, karibuni – Welcome

Swahili, or Kiswahili, belongs to the larger Benue-Congo branch of the Niger-Congo language family. The name comes from the plural of the Arabic word sawāhil ‘coast’. ‘Ki-‘ is a prefix attached to nouns of the noun class that includes languages. Swahili is spoken in East Africa by different people along the coast from Somalia to Mozambique. It serves as a lingua franca for most of East Africa.



The status of Swahili as an international language results from its strategic location on the coast of East Africa. The Swahili-speaking populations on the East African coast served as intermediaries between the Bantu-speaking peoples in the interior of Africa and the traders on the coast who came from South Asia and Arabia. The use of Swahili spread with the growth of commerce during the colonial period in the 19th-20th centuries. British control of important Swahili-speaking areas of Kenya and Tanzania resulted in the development of an international standard Swahili that was based on the educated speech of the island of  Zanzibar

Swahili is spoken by 15.5 million people as a first or as a second language (Ethnologue). Along with English, it is the official language of TanzaniaKenya, and Uganda, and is the only African language of the African Union Swahili is also spoken in BurundiMalawiMozambiqueRwandaSomaliaSouth AfricaUgandaUnited Arab Emirates, and the U.S. (Ethnologue). Most speakers of Swahili use it as a language of wider communication in addition to their home language or languages spoken in their immediate communities. While English still plays an important role in post-colonial East Africa today, Swahili is becoming more important in politics, commerce, culture, education, and mass media. Its growth is most notable in the working class population of East African urban centers  Notably, Swahili is the only African language among the official working languages of the African Union.


Swahili has a relatively large number of mostly mutually intelligible varieties that are listed below (Ethnologue). This can be explained by the fact that it is spoken in many different countries.

  • Kiunguja which originated on the island of Zanzibar is considered to be the standard.
  • Mambrui (Malindi)
  • Mgao (Kimgao)
  • Mrima (Mtang’ata)
  • Pemba
  • Unguja (Kiunguja, Zanzibar).


Sound system

The sound system of Swahili shares a number of features with other Niger-Congo languages. It has 5 vowel and 36 consonant phonemes. The language has a simple syllable structure with syllables typically ending in a vowel with no consonant clusters and no final consonants. A vowel is added to loanwords that end in a consonant, e.g., English bank becomes benki in Swahili.

Swahili has five vowel phonemes, i.e., sounds that can serve to differentiate word meaning. There are no diphthongs. Vowel sequences are permitted.




  • The most unusual feature of Swahili consonants are implosive sounds that are produced with the air being inhaled, rather than being expelled from the lungs.
  • Another unusual feature are prenasalized consonants that are produced as phonological units that combine a nasal with a stop or fricative.
  • /m/ can be syllable-forming, e.g., mti ‘tree’.

  • /pʰ, tʰ, kʰ,  tʃʰ/ are aspirated consonants released with a strong puff of air. Aspiration is marked with a raised ʰ
  • /ᵐb, ᵑd, ᵑɟ, ᵑg, ᶬv , ᵑz/ are prenasalized consonants
  • /ɓ, ɗ, ʄ, ɠ/ are implosive stops that have no equivalents in English. Implosive consonants are produced by inhaling rather than exhaling air from the lungs
  • /θ/ = th in think
  • /ð/ = th in that
  • /x, ɣ/ have no equivalents in English
  • /ʃ/ = sh in shop
  • /tʃ/ = ch in chop
  • /ɲ/ = first in canyon
  • /ŋ/ = ng in song
  • /j/ = y in yet


Stress in Swahili words normally falls on the penultimate (one before last) syllable. Unlike other Bantu languages, Swahili does not have tones.


Swahili is an agglutinative language, i.e., grammatical functions are expressed by adding prefixes and suffixes to roots.


Swahili nouns belong to 15 different classes, a feature common to Bantu languages. Six classes usually indicate singular nouns, five usually indicate plural nouns, one class indicates abstract nouns, one class indicate verbal infinitives used as nouns, and three classes indicate location. Each class has a different set of prefixes for marking numbers (singular and plural). Some noun classes can be semantically defined. For instance, nouns beginning with m– in the singular and wa– in the plural denote animate beings, especially people, e.g., mtoto ‘child, ‘watoto ‘children’. The same prefixes are attached to adjectives and numerals that follow nouns, e.g., mtoto mmoja ‘child one’, ‘watoto wawili ‘children two’. Loanwords are assimilated into the noun classes.


Swahili verbs consist of a root plus prefixes that represent various verbal categories such as person and tense. Verb complexes subsume subject pronouns which are incorporated into the verb.

ninakata ‘I am cutting’
Present progressive
sikati ‘I am not cutting’
negative prefix for ‘I’
negative suffix
umekata ‘you have cut’
‘past perfect’
ukimekata ‘if you had cut’


Word order
The normal word order in Swahili is Verb Complex-Object. Modifiers follow nouns.


The bulk of Swahili vocabulary is Bantu in origin. In addition, many Swahili words are borrowings from Arabic and Persian as a result of contact with Arab and Persian traders. The language has also borrowed extensively from Portuguese and German during the colonial period, and most recently from English.

Below are some common words and phrases in Swahili.

Hello Jambo
Goodbye Kwa heri (to one person), kwa herini (to more than one person)
Thank you Asante (to one person), asanteni (to more than one person)
Please Tafadhali
Excuse me Samahani
Yes Ndiyo
No Siyo / Hapana
Man Mwanamume
Woman Mwanamke


Below are Swahili numerals 1-10.



Swahili has a long literary tradition dating back to the middle of the 17th century. The oldest surviving documents written in Swahili date back to the early part of the 18th century. They were transcriptions of oral Swahili epic poetry written in the Arabic script, the result of of Islamic influence on the culture of East Africa. Many works of Western writers have been translated into Swahili. The most famous contemporary Swahili author is Shaaban Robert, a Tanzanian writer known for his novels. Swahili was originally written in the Arabic script that was replaced by a Roman-based alphabet in the mid-19th century. The alphabet was standardized in the 1930s.

Take a look at Article 1 of the Universal Declaration of Human Rights in Swahili.

Kifungu cha 1.
Watu wote wamezaliwa huru, hadhi na haki zao ni sawa. Wote wamejaliwa akili na dhamiri, hivyo yapasa watendeane kindugu.
Article 1
All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.

    Thanks for this information. I’ve been looking for it. But, I have a question, is Swahili fixed to the SVO word order or to other structure.
    I have had a hard time trying to find about it.

  2. Bill

    You improperly used “ninakatai” for the negation.

    • Irene Thompson

      Thank you for the comment. Please give us the correct form.

      • Mike


        • Irene Thompson

          Please elaborate what you are trying to convey.

  3. Daniel Anderson

    Instead of using ninakatai, the proper conjugation would be si (negative prefix for “I”)+ kat(drop the a)+i (negative suffix)so all together you have the word Sikati=I am not cutting.

      Thank you for the input. We will make the correction.

    Thanks a lot for an additional post. I’m very happy to be able to
    get that kind of information.

    Not sure if I’m correct in saying this, but the table with the Consonant Phonemes lists [v] and [f] as bilabial fricatives– these are labio-dental fricatives. [β] is actually the voiced bilabial fricative. Also, [θ] and [ð] are not labio-dental, but rather interdental (or just plain dental).

    its true and thanx for your lessons but how do
    learn how to speak it fluently

    • Irene Thompson

      The same way you learn to speak any second language fluently. Study it for several years, then spend a lot of time in the company of native speakers or live in the country where the language is spoken for an extended period of time. There is no easy way, unless you are a young child.

    Thank you for this description. However, Kiswahili does not have implosive phonemes. It does rely on the eggressive pulmonic mechanism
