Swahili, also known as Kiswahili, is a Bantu language widely spoken in East Africa. With over 16 million native speakers and around 80 million speakers overall, it serves as a lingua franca in countries such as Kenya, Tanzania, Uganda, and the Democratic Republic of Congo. Swahili’s grammar is particularly fascinating due to its unique characteristics and the influences it has absorbed from Arabic, Portuguese, German, and English over centuries. This article delves into the special aspects of Swahili grammar, exploring its structure, rules, and idiosyncrasies.

Noun Classes and Agreement

One of the most distinctive features of Swahili grammar is its noun class system. Unlike languages that use gendered nouns, Swahili employs a system where nouns are categorized into various classes. Each class comes with its own prefixes and influences the agreement of adjectives, verbs, and other parts of speech.

Noun Classes:
Swahili has 18 noun classes, but commonly, only 15 are actively used. These classes are identified by specific prefixes. For example:
– **Class 1/2 (M-Wa):** This class typically includes people. E.g., *mtu* (person) and *watu* (people).
– **Class 3/4 (M-Mi):** Often includes trees and natural phenomena. E.g., *mti* (tree) and *miti* (trees).
– **Class 5/6 (Ji-Ma):** Generally encompasses inanimate objects and augmentatives. E.g., *jicho* (eye) and *macho* (eyes).
– **Class 7/8 (Ki-Vi):** Includes tools and diminutives. E.g., *kiti* (chair) and *viti* (chairs).
– **Class 9/10 (N-N):** Covers animals, among other things. E.g., *ndege* (bird/birds).

Agreement:
Swahili nouns dictate the form of other words in a sentence:
– **Adjectives:** Must agree with the noun class. E.g., *mtu mzuri* (a good person) vs. *kitabu kizuri* (a good book).
– **Verbs:** Verbs also take prefixes that agree with the noun class. E.g., *mtu anakula* (the person is eating) vs. *kitabu kinakula* (the book is eating, hypothetical).

Verb Structure

The verb structure in Swahili is another unique aspect of its grammar. Verbs are constructed with prefixes and suffixes that indicate tense, subject, and object, making them highly inflected and informative.

Basic Verb Form:
A Swahili verb consists of:
– **Subject Prefix:** Indicates the doer of the action. E.g., *ni-* (I), *u-* (you), *a-* (he/she).
– **Tense Marker:** Indicates when the action takes place. E.g., *li-* (past), *na-* (present), *ta-* (future).
– **Verb Root:** The main action. E.g., *-kula* (eat), *-soma* (read).
– **Object Marker (optional):** Indicates the receiver of the action. E.g., *-ni-* (me), *-ku-* (you).

Examples:
– **Present Tense:** *Ninakula* (I am eating).
– **Past Tense:** *Nilisoma* (I read).
– **Future Tense:** *Nitalala* (I will sleep).

Tense and Aspect

Swahili verbs are marked for both tense and aspect, providing detailed information about the timing and nature of the action.

Tense:
– **Present:** Expressed with the marker *na-*. E.g., *ninakimbia* (I am running).
– **Past:** Indicated by *li-*. E.g., *nilipika* (I cooked).
– **Future:** Marked by *ta-*. E.g., *nitakwenda* (I will go).

Aspect:
– **Perfective:** Uses the marker *me-*. E.g., *nimefanya* (I have done).
– **Habitual:** Expressed with *hu-*. E.g., *hukimbia* (he/she usually runs).

Negation

Negation in Swahili involves modifying the verb form to indicate a negative action.

Present Tense Negation:
– The subject prefix changes: *ni-* becomes *si-*.
– The tense marker *na-* is dropped.
– The verb root remains the same.
– E.g., *Sikula* (I am not eating).

Past Tense Negation:
– The subject prefix changes: *ni-* becomes *si-*.
– The tense marker *li-* becomes *ku-*.
– E.g., *Sikupika* (I did not cook).

Future Tense Negation:
– The subject prefix changes: *ni-* becomes *si-*.
– The tense marker *ta-* becomes *ta-kuwa*.
– E.g., *Sitakuwa* (I will not be).

Pronouns and Possessives

Swahili pronouns and possessive forms are relatively straightforward but must agree with the noun class they refer to.

Subject Pronouns:
– **I:** *mimi*
– **You (singular):** *wewe*
– **He/She:** *yeye*
– **We:** *sisi*
– **You (plural):** *nyinyi*

Adjectives and Adverbs

Adjectives and adverbs in Swahili must agree with the noun they describe, adhering to the noun class system.

Adjective Agreement:
– Adjectives take prefixes that match the noun class. E.g., *mtoto mzuri* (a good child), *kitabu kizuri* (a good book).

Common Adjectives:
– **Big:** *kubwa*
– **Small:** *ndogo*
– **Good:** *zuri*

Adverbs:
– Adverbs do not change according to the noun class. E.g., *haraka* (quickly), *polepole* (slowly).

Examples:
– **I am eating and drinking:** *Ninakula na kunywa.*

Reduplication

Reduplication in Swahili is used to emphasize or alter the meaning of words, often to indicate intensity or repetition.

Examples:
– **Slowly:** *polepole* (from *pole* – slow)
– **Very small:** *ndogondogo* (from *ndogo* – small)

Loanwords and Influences

Swahili has borrowed extensively from other languages, enriching its vocabulary and making it unique.

Arabic Influence:
Due to historical trade relations, many Swahili words are of Arabic origin. E.g., *kitabu* (book) from Arabic *kitāb*.

Portuguese Influence:
Words from Portuguese entered Swahili during colonial times. E.g., *meza* (table) from Portuguese *mesa*.

English Influence:
Modern Swahili includes many English loanwords, especially in technology and education. E.g., *kompyuta* (computer).

Idiomatic Expressions

Swahili is rich in idiomatic expressions that convey cultural and contextual meanings beyond the literal interpretation of the words.
