Appendix:Proto-Germanic nouns
Proto-Germanic nouns are declined according to number (singular and plural) and case (nominative, vocative, accusative, genitive, dative and instrumental). Furthermore, each noun has an assigned gender, which determines the inflection of that noun but also of any pronouns or adjectives that modify or refer to that noun. There are three genders: masculine, feminine and neuter. Often but not always, the gender can be determined from the nominative singular form of the noun. Additionally, the nominative and vocative plural forms are always alike, and neuter nouns have only a single form for the nominative, vocative and accusative cases.
Nouns can be divided into several declension classes based on the formation of the case-and-number endings. Globally, there are vowel stems (a-, ō-, i- and u-stems) and consonant stems (n-, r- and z-stems and stems ending in other consonants). Usually, only nouns ending in consonants other than n, r or z are called consonant stems. Additionally, the a-, ō- and an-stems could be preceded by -j-; these ja-, jō- and jan-stems were not very different from their normal counterparts in Proto-Germanic but diverged (often radically) in the daughter languages.
a-stems
editThe a-stems descend from Proto-Indo-European thematic nouns, and are the most common type of noun in Proto-Germanic. They can be either masculine (ending in -az) or neuter (ending in -ą, nasal a). The two genders differ only in the nominative, vocative and accusative cases; the other three cases are identical for both.
The genitive singular *-as is unusual in that it does not display the expected effects of Verner's law. It was likely imported from the genitive pronoun *þas via the a-stem adjectives.
| masculine | neuter | |||
|---|---|---|---|---|
| singular | plural | singular | plural | |
| nominative | *-az | *-ōz, *-ōs | *-ą | *-ō |
| vocative | *-∅[n 1] | *-ōz, *-ōs | *-ą | *-ō |

| dative | *-ai | *-amaz | *-ai | *-amaz |
| instrumental | *-ō | *-amiz | *-ō | *-amiz |
ō-stems
editThe ō-stems descend from PIE thematic feminine nouns in *-eh₂, as well as neuter plurals that were reinterpreted as feminine singulars. They are also common, and are always feminine, with the nominative singular ending in -ō. They are the feminine equivalent of the a-stems.

| accusative | *-ǭ | *-ōz |
| genitive | *-ōz | *-ǫ̂ |
| dative | *-ōi | *-ōmaz |
| instrumental | *-ō | *-ōmiz |
ī/jō-stems
editThe ī/jō stems are a small group of inherited feminine nouns that inflect mostly as jō-stems, but which have a nominative and vocative singular ending in -ī instead of -jō. They descend from PIE proterokinetic feminines in -ih₂-/-yéh₂-.

| singular | plural | |
| nominative | *-ī | *-(i)jôz |
| vocative | *-ī | *-(i)jôz |

| genitive | *-(i)jōz | *-(i)jǫ̂ |
| dative | *-(i)jōi | *-(i)jōmaz |
| instrumental | *-(i)jō | *-(i)jōmiz |
i-stems
editThe i-stems are reasonably common, and appear in all three genders, although neuter i-stems are very rare. The masculine and feminine i-stems are declined the same, with a nominative singular in -iz. The neuters end in -i.
| masculine/feminine | neuter | |||

| dative | *-ī | *-imaz | *-ī | *-imaz |
| instrumental | *-ī | *-imiz | *-ī | *-imiz |
u-stems
editThe u-stems are fairly common, and are mostly analogous to i-stems. The masculine and feminine are identical, ending in -uz. Neuters are very rare, and end in -u.
| masculine/feminine | neuter | |||
|---|---|---|---|---|
| singular | plural | singular | plural | |
| nominative | *-uz | *-iwiz | *-u | *-ū |

| genitive | *-auz | *-iwǫ̂ | *-auz | *-iwǫ̂ |
| dative | *-iwi | *-umaz | *-iwi | *-umaz |
| instrumental | *-ū | *-umiz | *-ū | *-umiz |
an-stems
editThe an-stems are a common group of noun and are either masculine or neuter, although neuters are limited to a small handful of inherited forms. The nominative singular end in -ô (overlong).
| masculine | neuter | |||
|---|---|---|---|---|
| singular | plural | singular | plural | |
| nominative | *-ô | *-aniz | *-ô | *-ōnō |
| vocative | *-ô | *-aniz | *-ô | *-ōnō |

| genitive | *-iniz | *-anǫ̂ | *-iniz | *-anǫ̂ |
| dative | *-ini | *-ammaz | *-ini | *-ammaz |
| instrumental | *-inē | *-ammiz | *-inē | *-ammiz |
ōn-stems
editThe ōn-stems are an innovative Germanic formation, created by adding n-stem endings to ō-stems. They are also common and are always feminine, ending in -ǭ (long nasal o). They are the feminine counterpart of the an-stems, just like ō-stems are the feminine counterpart of a-stems.

| genitive | *-ōniz | *-ōnǫ̂ |
| dative | *-ōni | *-ōmaz |
| instrumental | *-ōnē | *-ōmiz |
īn-stems
editThis group of nouns contains only a single type of abstract noun, formed by attaching the suffix *-į̄ to adjectives. They are always feminine, and are essentially identical to ōn-stems, with ī replacing ō in all the forms. The nominative singular ends in -į̄ (long nasal i).

| genitive | *-īniz | *-īnǫ̂ |
| dative | *-īni | *-īmaz |
| instrumental | *-īnē | *-īmiz |
r-stems
editThe r-stems are limited only to a group of seven close kinship terms: *fadēr (“father”), *mōdēr (“mother”), *brōþēr (“brother”), *swestēr (“sister”), *duhtēr (“daughter”), *þeuhtēr (“grandson”), and *aihtēr (“owner”). Their inflection generally resembled the other consonant stems.

| accusative | *-erų | *-runz |
| genitive | *-urz | *-rǫ̂ |
| dative | *-ri | *-rumaz |
| instrumental | *-rē | *-rumiz |
z-stems
editThe z-stems are fairly rare, and are always neuter. They are formed similar to an-stems, but with z replacing n. Their nominative singular forms end in -az, like masculine a-stems.

|---|---|---|
| singular | plural | |
| nominative | *-az | *-izō |
| vocative | *-az | *-izō |
| accusative | *-az | *-izō |
| genitive | *-iziz | *-izǫ̂ |
| dative | *-izi | *-izumaz |
| instrumental | *-izē | *-izumiz |
Other consonant stems
editNouns in this group are usually just called "consonant stems". It is mostly a class of remnants, consisting of root nouns (nouns with no suffix) and nouns with a suffix ending in a consonant other than n, r or z. They can be any gender, and masculine and feminine are identical, with nominative singular forms ending in -s or -z based on the voicing of the previous consonant, theoretically. However, no language would reflect separate reflexes, and all Northwest Germanic reflexes come from *-z by analogy (the distinction obscured by Gothic by final devoicing), so *fōts (“foot”) could have the variant *fōtz.
There are few reconstructible neuters; those that can be reconstructed are irregular and have no ending in the nominative singular. It is possible that many a-stem neuters actually or originally belonged to this class, however.
