<!-- language families sorted alphabetically -->

=== Algonquian languages ===
The [[Ojibwe language]] and other members of the [[Algonquian languages]] distinguish between animate and inanimate classes. Some sources argue that the distinction is between things which are powerful and things which are not. Living things, as well as sacred things and things connected to the Earth, are considered powerful and belong to the animate class. Still, the assignment is somewhat arbitrary, as "[[raspberry]]" is animate, but "[[strawberry]]" is inanimate.

=== Athabaskan languages ===
In [[Navajo language|Navajo]] ([[Southern Athabaskan languages|Southern Athabaskan]]) nouns are classified according to their animacy, shape, and consistency. [[Morphology (linguistics)|Morphologically]], however, the distinctions are not expressed on the nouns themselves, but on the verbs of which the nouns are the subject or direct object. For example, in the sentence ''{{spell-nv|Shi’éé’ tsásk’eh bikáa’gi dah siłtsooz}}'' "My shirt is lying on the bed", the verb {{spell-nv|siłtsooz}} "lies" is used because the subject ''{{spell-nv|shi’éé’}}'' "my shirt" is a flat, flexible object. In the sentence {{spell-nv|Siziiz tsásk’eh bikáa’gi dah silá}} "My belt is lying on the bed", the verb ''{{spell-nv|silá}}'' "lies" is used because the subject ''{{spell-nv|siziiz}}'' "my belt" is a slender, flexible object.

[[Koyukon language|Koyukon]] ([[Northern Athabaskan languages|Northern Athabaskan]]) has a more intricate system of classification. Like Navajo, it has classificatory verb stems that classify nouns according to animacy, shape, and consistency. However, in addition to these verb stems, Koyukon verbs have what are called "gender prefixes" that further classify nouns. That is, Koyukon has two different systems that classify nouns: '''(a)''' a classificatory verb system and '''(b)''' a gender system. To illustrate, the verb stem ''-tonh'' is used for enclosed objects. When ''-tonh'' is combined with different gender prefixes, it can result in ''daaltonh'' which refers to objects enclosed in boxes or ''etltonh'' which refers to objects enclosed in bags.

=== Australian Aboriginal languages ===
The [[Dyirbal language]] is well known for its system of four noun classes, which tend to be divided along the following semantic lines:{{sfn|Corbett|1991|p=15}}

{{Ordered list |list_style_type=upper-roman
|animate objects, men
|women, [[water]], [[fire]], [[violence]]
|edible [[fruit]] and [[vegetable]]s
|miscellaneous (includes things not classifiable in the first three)
}}

The class usually labeled "feminine", for instance, includes the word for fire and nouns relating to fire, as well as all dangerous creatures and phenomena. (This inspired the title of the [[George Lakoff]] book ''[[Women, Fire, and Dangerous Things]]''.)

The [[Ngangikurrunggurr language]] has noun classes reserved for canines and hunting weapons. The [[Anindilyakwa language]] has a noun class for things that reflect light. The [[Diyari language]] distinguishes only between female and other objects. Perhaps the most noun classes in any Australian language are found in [[Yanyuwa language|Yanyuwa]], which has 16 noun classes, including nouns associated with food, trees and abstractions, in addition to separate classes for men and masculine things, women and feminine things. In the men's dialect, the classes for men and for masculine things have simplified to a single class, marked the same way as the women's dialect marker reserved exclusively for men.<ref>Jean F Kirton.

===Basque===
[[Basque language|Basque]] has two classes, animate and inanimate; however, the only difference is in the declension of locative cases (inessive, ablative, allative, terminal allative, and directional allative). For inanimate nouns, the locative case endings are attached directly if the noun is singular, and plural and indefinite number are marked by the suffixes ''-eta-'' and ''-(e)ta-'', respectively, before the case ending (this is in contrast to the non-locative cases, which follow a different system of number marking where the indefinite form of the ending is the most basic). For example, the noun ''etxe'' "house" has the singular ablative form ''etxetik'' "from the house", the plural ablative form ''etxeetatik'' "from the houses", and the indefinite ablative form ''etxetatik'' (the indefinite form is mainly used with determiners that precede the noun: ''zenbat etxetatik'' "from how many houses"). For animate nouns, on the other hand, the locative case endings are attached (with some phonetic adjustments) to the suffix ''-gan-'', which is itself attached to the singular, plural, or indefinite genitive case ending. Alternatively, ''-gan-'' may attach to the absolutive case form of the word if it ends in a vowel. For example, the noun ''ume'' "child" has the singular ablative form ''umearengandik'' or ''umeagandik'' "from the child", the plural ablative form ''umeengandik'' "from the children", and the indefinite ablative form ''umerengandik'' or ''umegandik'' (cf. the genitive forms ''umearen'', ''umeen'', and ''umeren'' and the absolutive forms ''umea'', ''umeak'', and ''ume''). In the inessive case, the case suffix is replaced entirely by ''-gan'' for animate nouns (compare ''etxean'' "in/at the house" and ''umearengan''/''umeagan'' "in/at the child").

=== Caucasian languages ===
Some members of the [[Northwest Caucasian languages|Northwest Caucasian]] family, and almost all of the [[Northeast Caucasian languages]], manifest noun class. In the Northeast Caucasian family, only [[Lezgian language|Lezgian]], [[Udi language|Udi]], and [[Aghul language|Aghul]] do not have noun classes. Some languages have only two classes, whereas [[Bats language|Bats]] has eight. The most widespread system, however, has four classes: male, female, animate beings and certain objects, and finally a class for the remaining nouns. The [[Andi language]] has a noun class reserved for insects.

Among Northwest Caucasian languages, only [[Abkhaz language|Abkhaz]] and [[Abaza language|Abaza]] have noun class, making use of a human male/human female/non-human distinction.

In all Caucasian languages that manifest class, it is not marked on the noun itself but on the dependent verbs, adjectives, pronouns and postpositions or prepositions.

=== Atlantic–Congo languages ===
[[Atlantic–Congo languages]] can have ten or more noun classes, defined according to non-sexual criteria. Certain nominal classes are reserved for humans. The [[Fula language]] has about 26 noun classes (the exact number varies slightly by dialect).

==== Bantu languages ====
According to [[Carl Meinhof]], the [[Bantu languages]] have a total of 22 noun classes called '''nominal classes''' (this notion was introduced by [[Wilhelm Bleek|W.&nbsp;H.&nbsp;I. Bleek]]). While no single language is known to express all of them, most of them have at least 10 noun classes. For example, by Meinhof's numbering, [[Shona language|Shona]] has 20 classes, [[Swahili language#Noun classes|Swahili]] has 15, [[Sesotho nouns#Noun prefix system|Sotho]] has 18 and [[Luganda#Noun classes|Ganda]] has 17.

Additionally, there are '''polyplural noun classes'''. A polyplural noun class is a plural class for more than one singular class.<ref>{{cite web|url=http://www.african.gu.se/aa/pdfs/aa03161.pdf|title=Remarks on a few "polyplural" classes in Bantu|access-date=2014-03-06|archive-date=2009-12-11|archive-url=https://web.archive.org/web/20091211012440/http://www.african.gu.se/aa/pdfs/aa03161.pdf|url-status=dead}}</ref> For example, [[Proto-Bantu language|Proto-Bantu]] class 10 contains plurals of class 9 nouns and class 11 nouns, while class 6 contains plurals of class 5 nouns and class 15 nouns. Classes 6 and 10 are inherited as polyplural classes by most surviving Bantu languages, but many languages have developed new polyplural classes that are not widely shared by other languages.

Specialists in Bantu emphasize that there is a clear difference between genders (such as known from [[Afro-Asiatic languages|Afro-Asiatic]] and [[Indo-European languages|Indo-European]]) and nominal classes (such as known from Niger–Congo). Languages with nominal classes divide nouns formally on the base of [[Hyponymy|hyperonymic]] meanings. The category of nominal class replaces not only the category of gender, but also the categories of [[number]] and [[Grammatical case|case]].

Critics of Meinhof's approach notice that his numbering system of nominal classes counts singular and plural numbers of the same noun as belonging to separate classes. This seems to them to be inconsistent with the way other languages are traditionally considered, where number is orthogonal to gender (according to the critics, a Meinhof-style analysis would give [[Ancient Greek]] 9 genders). If one follows broader linguistic tradition and counts singular and plural as belonging to the same class, then Swahili has 8 or 9 noun classes, Sotho has 11 and Ganda has 10.

The Meinhof numbering tends to be used in scientific works dealing with comparisons of different Bantu languages. For instance, in [[Swahili language|Swahili]] the word {{lang|sw|rafiki}} 'friend' belongs to the class 9 and its "plural form" is {{lang|sw|marafiki}} of the class 6, even if most nouns of the 9 class have the plural of the class 10.  For this reason, noun classes are often referred to by combining their singular and plural forms, e.g., {{lang|sw|rafiki}} would be classified as "9/6", indicating that it takes class 9 in the singular, and class 6 in the plural.

However not all Bantu languages have these exceptions. In [[Luganda|Ganda]] each singular class has a corresponding plural class (apart from one class which has no singular–plural distinction; also some plural classes correspond to more than one singular class) and there are no exceptions as there are in Swahili. For this reason Ganda linguists use the orthogonal numbering system when discussing Ganda grammar (other than in the context of [[Bantu language|Bantu]] [[comparative linguistics]]), giving the 10 traditional noun classes of that language.

The distinction between genders and nominal classes is blurred still further by Indo-European languages that have nouns that behave like Swahili's {{lang|sw|rafiki}}. [[Italian language|Italian]], for example, has a group of nouns deriving from [[Latin language|Latin]] neuter nouns that acts as masculine in the singular but feminine in the plural: {{lang|it|il braccio}}/{{lang|it|le braccia}}; {{lang|it|l'uovo}}/{{lang|it|le uova}}. (These nouns are still placed in a neuter gender of their own by some grammarians.)

"Ø-" means [[Null morpheme|no prefix]]. Some classes are [[homonym]]ous (esp. 9 and 10). The Proto-Bantu class 12 disappeared in Swahili, class 13 merged with 7, and 14 with 11.

Class prefixes appear also on adjectives and verbs, e.g.:
{{interlinear|indent=3| lang = sw
|'''Ki'''tabu '''ki'''kubwa '''ki'''naanguka.
|CL7-book CL7-big CL7-PRS-fall
|'The big book falls.'}}

The [[Marker (linguistics)|class markers]] which appear on the adjectives and verbs may differ from the noun prefixes: 
{{interlinear|indent=3| lang = sw
|'''M'''toto '''wa'''ngu '''a'''linunua '''ki'''tabu.
|CL1-child CL1-my CL1-PST-CL7-buy CL7-book
|'My child bought a book.'}}

In this example, the verbal prefix '''{{lang|sw|a-}}''' and the pronominal prefix '''{{lang|sw|wa-}}''' are in concordance with the noun prefix '''{{lang|sw|m-}}''': they all express class 1 despite their different forms.

==== Zande ====
The [[Zande language]] distinguishes four noun classes:{{sfn|Corbett|1991|p=14}}

{| class="wikitable"
!Criterion!!Example!!Translation
|-
|human (male)||kumba||man
|-
|human (female)||dia||wife
|-
|animate||nya||beast
|-
|other||bambu||house
|}

There are about 80 inanimate nouns which are in the animate class, including nouns denoting heavenly objects (moon, rainbow), metal objects (hammer, ring), edible plants (sweet potato, pea), and non-metallic objects (whistle, ball). Many of the exceptions have a round shape, and some can be explained by the role they play in Zande mythology.
