Weak nouns
Weak nouns have declensions centered around a consonant -π½- which is not displayed in the nominative singular, but appears in all other forms. Weak noun declension forms are identical to those of the weak (definite) adjectives.
Weak nouns undergo their specific ablauting in the suffixes, which is different from the consonant stem noun ablauts:
- Non-oblique singulars are not ablauted
- All oblique singulars (both old and new) are ablauted
- All duals are ablauted
- Plurals are not ablauted
A-subgroup
- Masculine an-stem, ends with -π° in nominative singular.
- Feminine Εn-stem, ends with -π in nominative singular.
- Neuter an-stem, ends with -π in nominative singular.
I-subgroup
- Masculine in-stem, ends with -πΉ in nominative singular.
- Feminine Δ«n-stem, ends with -π΄πΉ in nominative singular.
- Neuter in-stem, ends with -π΄ in nominative singular.
U-subgroup
- Masculine un-stem, ends with -πΏ in nominative singular.
- Feminine Ε«n-stem, ends with -πΏΜ in nominative singular.
- Neuter un-stem, ends with -π°Μ in nominative singular.
N-stems (a subgroup of consonant stems, also found in Gothic as some irregular neuter an-stems) are unrelated to weak nouns and follow the consonant stem ablauting and case formation rules.
