Noun classes Swahili nouns are separable into
classes, which are roughly analogous to
genders in other languages. In Swahili,
prefixes mark groups of similar objects: marks single human beings ( 'child'), marks multiple humans ( 'children'), marks abstract nouns ( 'childhood'), and so on. And just as adjectives and pronouns must agree with the gender of nouns in some languages with grammatical gender, so in Swahili adjectives, pronouns and even verbs must agree with nouns. This is a characteristic feature of all the
Bantu languages.
Semantic motivation The
ki-/vi- class historically consisted of two separate genders, artefacts (Bantu class 7/8, utensils and hand tools mostly) and diminutives (Bantu class 12/13), which were conflated at a stage ancestral to Swahili. Examples of the former are
kisu "knife",
kiti "chair" (from
mti "tree, wood"),
chombo "vessel" (a contraction of
ki-ombo). Examples of the latter are
kitoto "infant", from
mtoto "child";
kitawi "frond", from
tawi "branch"; and
chumba (
ki-umba) "room", from
nyumba "house". It is the diminutive sense that has been furthest extended. An extension common to diminutives in many languages is
approximation and
resemblance (having a 'little bit' of some characteristic, like
-y or
-ish in English). For example, there is
kijani "green", from
jani "leaf" (compare English 'leafy'),
kichaka "bush" from
chaka "clump", and
kivuli "shadow" from
uvuli "shade". A 'little bit' of a verb would be an instance of an action, and such
instantiations (usually not very active ones) are found:
kifo "death", from the verb
-fa "to die";
kiota "nest" from
-ota "to brood";
chakula "food" from
kula "to eat";
kivuko "a ford, a pass" from
-vuka "to cross"; and
kilimia "the
Pleiades", from
-limia "to farm with", from its role in guiding planting. A resemblance, or being a bit like something, implies marginal status in a category, so things that are marginal examples of their class may take the
ki-/vi- prefixes. One example is
chura (
ki-ura) "frog", which is only half terrestrial and therefore is marginal as an animal. This extension may account for disabilities as well:
kilema "a cripple",
kipofu "a blind person",
kiziwi "a deaf person". Finally, diminutives often denote contempt, and contempt is sometimes expressed against things that are dangerous. This might be the historical explanation for
kifaru "
rhinoceros",
kingugwa "
spotted hyena", and
kiboko "
hippopotamus" (perhaps originally meaning "stubby legs"). Another class with broad semantic extension is the
m-/mi- class (Bantu classes 3/4). This is often called the 'tree' class, because
mti, miti "tree(s)" is the prototypical example. However, it seems to cover vital entities neither human nor typical animals: trees and other plants, such as
mwitu 'forest' and
mtama 'millet' (and from there, things made from plants, like
mkeka 'mat'); supernatural and natural forces, such as
mwezi 'moon',
mlima 'mountain',
mto 'river'; active things, such as
moto 'fire', including active body parts (
moyo 'heart',
mkono 'hand, arm'); and human groups, which are vital but not themselves human, such as
mji 'village', and, by analogy,
mzinga 'beehive/cannon'. From the central idea of
tree, which is thin, tall, and spreading, comes an extension to other long or extended things or parts of things, such as
mwavuli 'umbrella',
moshi 'smoke',
msumari 'nail'; and from activity there even come active instantiations of verbs, such as
mfuo "metal forging", from
-fua "to forge", or
mlio "a sound", from
-lia "to make a sound". Words may be connected to their class by more than one metaphor. For example,
mkono is an active body part, and
mto is an active natural force, but they are also both long and thin. Things with a trajectory, such as
mpaka 'border' and
mwendo 'journey', are classified with long thin things, as in many other languages with noun classes. This may be further extended to anything dealing with time, such as
mwaka 'year' and perhaps
mshahara 'wages'. Animals exceptional in some way and so not easily fitting in the other classes may be placed in this class. The other classes have foundations that may at first seem similarly counterintuitive. In short, • Classes 1–2 include most words for people: kin terms, professions, ethnicities, etc., including translations of most English words ending in
-er. They include a couple of generic words for animals:
mnyama 'beast',
mdudu 'bug'. • Classes 5–6 have a broad semantic range of groups, expanses, and augmentatives. Although interrelated, it is easier to illustrate if broken down: • Augmentatives, such as
joka 'serpent' from
nyoka 'snake', lead to titles and other terms of respect (the opposite of diminutives, which lead to terms of contempt):
Bwana 'Sir',
shangazi 'aunt',
fundi 'craftsman',
kadhi 'judge' • Expanses:
ziwa 'lake',
bonde 'valley',
taifa 'country',
anga 'sky' • from this, mass nouns:
maji 'water',
vumbi 'dust' (and other liquids and fine particulates that may cover broad expanses),
kaa 'charcoal',
mali 'wealth',
maridhawa 'abundance' • Collectives:
kundi 'group',
kabila 'language/ethnic group',
jeshi 'army',
daraja ' stairs',
manyoya 'fur, feathers',
mapesa 'small change',
manyasi 'weeds',
jongoo 'millipede' (large set of legs),
marimba 'xylophone' (large set of keys) • from this, individual things found in groups:
jiwe 'stone',
tawi 'branch',
ua 'flower',
tunda 'fruit' (also the names of most fruits),
yai 'egg',
mapacha 'twins',
jino 'tooth',
tumbo 'stomach' (cf. English "guts"), and paired body parts such as
jicho 'eye',
bawa 'wing', etc. • also collective or dialogic actions, which occur among groups of people:
neno 'a word', from
kunena 'to speak' (and by extension, mental verbal processes:
wazo 'thought',
maana 'meaning');
pigo 'a stroke, blow', from
kupiga 'to hit';
gomvi 'a quarrel',
shauri 'advice, plan',
kosa 'mistake',
jambo 'affair',
penzi 'love',
jibu 'answer',
agano 'promise',
malipo 'payment' • From pairing, reproduction is suggested as another extension (fruit, egg, testicle, flower, twins, etc.), but these generally duplicate one or more of the subcategories above • Classes 9–10 are used for most typical animals:
ndege 'bird',
samaki 'fish', and the specific names of typical beasts, birds, and bugs. However, this is the 'other' class, for words not fitting well elsewhere, and about half of the class 9–10 nouns are foreign loanwords. Loans may be classified as 9–10 because they lack the prefixes inherent in other classes, and most native class 9–10 nouns have no prefix. Thus they do not form a coherent semantic class, though there are still semantic extensions from individual words. • Class 11 (which takes class 10 for the plural) are mostly nouns with an "extended outline shape", in either one dimension or two: • mass nouns that are generally localized rather than covering vast expanses:
uji 'porridge',
wali 'cooked rice' • broad:
ukuta 'wall',
ukucha 'fingernail',
upande 'side' (≈
ubavu 'rib'),
wavu 'net',
wayo 'sole, footprint',
ua 'fence, yard',
uteo 'winnowing basket' • long:
utambi 'wick',
utepe 'stripe',
uta 'bow',
ubavu 'rib',
ufa 'crack',
unywele 'a hair' • from 'a hair',
singulatives of nouns, which are often class 6 ('collectives') in the plural:
unyoya 'a feather',
uvumbi 'a mote of dust',
ushanga 'a bead'. • Class 14 are abstractions, such as
utoto 'childhood' (from
mtoto 'a child') and have no plural. They have the same prefixes and concord as class 11, except optionally for adjectival concord. • Class 15 are verbal infinitives. • Classes 16–18 are locatives. The Bantu nouns of these classes have been lost; the only permanent member is the Arabic loan
mahali 'place(s)', but in Mombasa Swahili, the old prefixes survive:
pahali 'place',
mwahali 'places'. However, any noun with the locative suffix
-ni takes class 16–18 agreement. The distinction between them is that class 16 agreement is used if the location is intended to be definite ("at"), class 17 if indefinite ("around") or involves motion ("to, toward"), and class 18 if it involves containment ("within"):
mahali pazuri 'a good spot',
mahali kuzuri 'a nice area',
mahali muzuri (it's nice in there).
Borrowing Borrowings may or may not be given a prefix corresponding to the semantic class they fall in. For example, Arabic ("bug, insect") was borrowed as
mdudu, plural
wadudu, with the class 1/2 prefixes
m- and
wa-, but Arabic ("fish scales", plural of ) and English
sloth were borrowed as simply
fulusi ("
mahi-mahi" fish) and
slothi ("
sloth"), with no prefix associated with animals (whether those of class 9/10 or 1/2). In the process of naturalization of borrowings within Swahili, loanwords are often reinterpreted, or reanalysed, as if they already contain a Swahili class prefix. In such cases the interpreted prefix is changed with the usual rules. Consider the following loanwords from Arabic: • The Swahili word for "book",
kitabu, is borrowed from Arabic
kitāb(un) "book" (plural ; from the Arabic root
k.t.b. "write"). However, the Swahili plural form of this word ("books") is
vitabu, following Bantu grammar in which the
ki- of
kitabu is reanalysed (reinterpreted) as a nominal class prefix whose plural is
vi- (class 7/8). ("Of" is animate
wa and inanimate
ya, za.) In Standard Swahili, human subjects and objects of whatever class trigger animacy concord in
a-, wa- and
m-, wa-, and non-human subjects and objects trigger a variety of gender-concord prefixes. ==Dialects and closely related languages==
