Appendix:Swahili noun classes

Swahili noun classes
Swahili nouns, like those in other Bantu languages, are noted for a system of semantically based classing, which affects not only nouns but also their modifiers (adjectives, numbers, demonstratives) and verbs. Just as gender accord is required in many Indo-European languages (e.g., French, Spanish, German, Russian), the modifiers and verbs associated with a given noun must show class agreement with the noun by using certain prefixes. This results in marked alliteration:
 * Watu wazuri wawili wale wameanguka (watu = people; -zuri = good; -wili = two; -le = those; -anguka = fall down)
 * Those two good people fell.

M-wa class
This class is also known as Class I (in the singular) and Class II (in the plural). It is used to refer to people almost solely; the two notable exceptions are and, which both serve to categorise animate objects. These prefixes may be added to adjective, noun, or verb stems to express the idea that a person has that characteristic, like →, or  →.

Adjectives agree with the same prefixes as the noun, but verbs agree with the prefix in the singular and  in the plural.


 * Prefix: , mw-, mu-
 *  — person.
 *  — child.


 * Plural prefix: , w-
 *  — people.
 *  — children.

M-mi class
This class is also known as Class III (in the singular) and Class IV (in the plural). It is used to refer to inanimates almost solely, but Swahili considers plants and groupings of animals or people to be inanimate. Natural phenomena and active body parts also belong in this category, as well as anything inanimate that has a connection to one of the concepts listed above, like an object made from a plant or shaped like one. These prefixes may be added to noun stems to express the name of a plant that bears a certain fruit, like →.

The extremely few animate nouns in the M-mi class take the concords of the M-wa class.

Adjectives agree with the same prefixes as the noun, but verbs agree with the prefix in the singular and  in the plural.


 * Prefix: , mw-, mu-
 *  — tree.
 *  — year.
 *  — cassava.


 * Plural prefix: , my-
 *  — trees.
 *  — years.
 *  — cassavas.

Ji-ma class
This class is also known as Class V (in the singular) and Class VI (in the plural). It is used to refer to a wide variety of items, especially the names of fruits (and other round things), and collectives, inanimate objects that are usually found in groups, like. Some of these collectives may only exist in the plural forms, and these usually refer to liquids or small things that can literally or metaphorically cover wide expanses. The Ji-ma class prefixes may be added to noun stems to express an augmentative, like →.

This class was originally used for foreign loanwords because the singular did not necessarily have a prefix, but such words are usually placed in the N class now, although they are often given Ma class concords and the plural by many speakers. Borrowings referring to people are still habitually placed in the Ma class because of animacy concerns. There are a few words in the U class that take a Ma class plural, and some N class words that may take a Ma class plural to indicate a collective grouping.

Animate nouns in the Ma class (principally those referring to people) take the concords of the M-wa class.

Adjectives take no prefix in the singular unless they begin with a vowel, and take in the plural, but verbs agree with the prefix  in the singular and  in the plural.


 * Prefix: , j-, or no prefix
 *  — giant.
 *  — egg.


 * Plural prefix: , m-
 *  — giants.
 *  — eggs.
 *  — water (no singular).

Ki-vi class
This class is also known as Class VII (in the singular) and Class VIII (in the plural). It is chiefly used to refer to artifacts and tools, which are inanimate objects manufactured by humans that do not belong in another class. These prefixes may be added to noun stems to express a diminutive, like →. The diminutive is also used for things which have some (but not all) of the qualities of another thing, which are the object of contempt or fear, or which have a physical defect (including people with disabilities). The singular prefix only is also used to form language names from places where the language is spoken, like →. The plural prefix is used to form regular adverbs, chiefly on adjectival stems.

Animate nouns in the Ki-vi class (principally those referring to people) take the concords of the M-wa class.

Adjectives and verbs both agree with the same prefixes as the noun. When the plural prefix is added to an adjective, it forms an adverb.


 * Prefix: , ch-
 *  — cripple.
 *  — book.
 *  — little baby.
 *  — room.


 * Plural prefix: , vy-
 *  — cripples.
 *  — books.
 *  — little babies.
 *  — rooms.
 *  — well (from -zuri, good, beautiful).

N class
This class is also known as Class IX (in the singular) and Class X (in the plural). It is used to refer to a wide variety of items, both animate and inanimate, including most names of animals and kinship terms. The prefix is preserved as is only before d, g, j, or z. If the stem begins with a vowel, the prefix changes to ny-. If the stem begins with b or w the prefixed form will begin with mb; if it begins with v, then mv; if it begins with l or r, then nd. If the stem is a monosyllable, these rules do not apply and n can stand in front of any consonant. In all other cases, there is no prefix.

This class is usually used for foreign loanwords referring to inanimates that do not fit easily into the noun class system, because the singular does not necessarily require a prefix and the plural form is the same as the singular form, although they are often given Ma class concords and the plural by many speakers. Some N class words may also take a Ma class plural to indicate a collective grouping.

Animate nouns in the N class (principally those referring to people and animals) take the concords of the M-wa class. There is an important exception with the possessive adjectives, which, for the N class only, take the N class concords instead of the M-wa concords their animacy would appear to require. In literary usage, this exception is true of people in both singular and plural, but for animals only in the plural.

Adjectives theoretically take the prefix for both singular and plural forms, but it drops out or changes the same way that it does for nouns, as detailed above. Verbs agree with the prefix in the singular and  in the plural.


 * Prefix: , ny-, m-, or no prefix
 *  — bird.
 *  — wine.
 *  — pencil.


 * Plural prefix: , ny-, m-, or no prefix (same as singular)
 *  — birds.
 *  — wines. Note mvinyo is sometimes placed in the m-mi class, in which case it takes the plural for that class instead.
 *  — pencils.

U class
This class is also known as Class XI (in the singular) and Class XII (in the plural) for countable nouns, and Class XIV for uncountable nouns. As can be seen from the numbering system, this is actually composed of two classes that have merged. The countable nouns usually refer to inanimate objects that are somehow extensions in one dimension or another, but there is variability in this. The uncountable nouns usually refer to qualities or abstractions, or to collectives that are localised in one place, but made up of many tiny components, like. These prefixes may be added to adjective or noun stems to express or, like  →. They are also added to stems to form the names of countries or religions, like →  or  →, but proper nouns do not necessarily take their class's concords.

The countable nouns take a plural by using Class XII, which as a class is sometimes considered as nonexistent, because it is impossible to distinguish from Class X, the plural of the N class. All the rules of prefixing to a noun stem apply when creating such plurals. The uncountable nouns, in the rare cases where they are not in fact uncountable (like ) will take a plural of the Ma class.

Adjectives agree with in the singular and  in the plural (subject to the rules governing that prefix detailed above). However, when the countable and uncountable nouns of this class were separate, the prefix was used for the uncountable ones; it is archaic now, but still found in some set phrases. Verbs agree with the prefix in the singular and  in the plural. Words that take a Ma class plural take the concords of the Ma class in the plural as well.


 * Prefix: , w-, uw-
 *  — theft.
 *  — England.
 *  — childhood.
 *  — rib.
 *  — thread.


 * Plural prefix:  (see N class above)
 *  — ribs.
 *  — threads.

Ku class
This class is also known as Class XV. It is used to form verbal nouns, equivalent to an infinitive or a gerund in a European language. It is prefixed to the verbal stem, like →.

Adjectives and verbs both agree with the same prefixes as the noun; all the prefixes are identical to those of the Ku locative class below, with which these should not be confused.


 * Prefix: , kw-
 *  — beating, to beat.
 *  — going, to go.

Wiktionary entries for nouns in this class can be found among the entries in Category:Swahili verb forms, and are listed as words marked as verbal nouns of the ku class.

Pa locative class
This class is also known as Class XVI. It is used to denote a definite locative, or a locative of a noun known to be in a certain place, and the only noun that belongs in and of itself to this class is and its alternative forms. Other nouns are given the general locative suffix, which makes an adverbial noun, and are considered to be in the Pa locative class if they are in or on a definite place.

Adjectives and verbs both agree with the prefix.


 * Prefix: 
 *  pamoja — one place.

Ku locative class
This class is also known as Class XVII. It is used to denote an indefinite locative, or a locative of a noun not known to be in a certain place, or which is in transit. Nouns are given the general locative suffix, which makes an adverbial noun, and are considered to be in the Ku locative class if they are in an indefinite place.

Adjectives and verbs both agree with the prefix ; all the prefixes are identical to those of the Ku class above, with which these should not be confused.


 * Prefix: , kw-
 * kule = there ('twende kule' = "let's go there")

Mu locative class
This class is also known as Class XVIII. It is used to denote a locative where something is within the three-dimensional confines of the noun, or sometimes alongside the noun. Nouns are given the general locative suffix, which makes an adverbial noun, and are considered to be in the Mu locative class if they are in a definite place inside the noun.

Adjectives and verbs both agree with the prefix.


 * Prefix: , m-
 * mule = in there ('maji yako mule' = "the water is in there")
