Casuma is a Germanic language spoken in western Europe. It is the official language in the Casum Republic, and a minority language in surrounding areas in England, France and Spain. 

General information[]

Casuma is a fusional nominative-accusative SVO language. It is spoken by approximately 90 million people in Casum and approximately 1 million in surrounding areas. It is an isolate within the Germanic language family. Notable features the retention of Proto-Germanic nasal vowels and the extremely conservative Germanic vocabulary. There are many loans in Casuma from Basque and the Celtic languages. Morphologically, Casuma has four noun cases and two grammatical numbers (three in the pronouns). In addition, verbs conjugate for person and number, three tenses, three moods, and two voices.  The three grammatical genders were only preserved in the pronouns.

Nouns in Casuma decline for four cases. 

  • the Nominative case is the unmodified form of a noun and denotes the subject.
  • the Accusative case marks the direct object
  •  the Dative case marks the indirect object
  • the Genetive case shows posession 

Nouns follow five different declension patterns depending on the ending of a noun: a noun can decline differently if it ends in a nasal consonant, a consonant other than a nasal, a front or near-front vowel, a central or back vowel, and a nasal vowel.

Nasal consonant endings[]

declension of döusn - "animal"
Singular Plural
Nominative döusn döusnÿs
Accusative döusni
Dative döusny döusnys
Genetive döusnu döusnam

Non-nasal consonant endings[]

declension of rÿpyblÿc - "republic"
Singular Plural
Nominative rÿpyblÿc rÿpyblÿcas
Dative rÿpyblÿcy rÿpyblÿcyn
Genetive rÿpyblÿcu rÿpyblÿcin

Front and near-front vowel endings[]

The only truncation in this type of declension occurs in the accusative singular. 

declension of rügi - "rye"
Singular Plural
Nominative rügi rügin
Accusative rüganų rüginu
Dative rügim rügi
Genetive rügini rügi

Central and back vowel endings[]

declension of räcny - "rain"
Singular Plural
Nominative räcny räcniwi
Accusative räcnų räcnun
Dative räcnaz räcnasi
Genetive räcnys räcniwǫ

Nasal vowel endings[]

In the nominative plural, the accusative, and the genetive singular, the nasal vowel will be replaced by it's non-nasal counterpart and then the bolded case ending will be added on. In the genetive plural -es will be infixed between the final consonant and the nasal vowel. In the dative case, the truncations will be the same no matter which nasal vowel the noun ends in. 

declension of bazą - "berry"
Singular Plural
Nominative bazą bazanis
Accusative bazanu bazanus
Dative baz bazaun
Genetive bazas bazesą


Adjectives in Casuma preceed the noun they modify and agree with it's case. There are two irregular adjectives (much) and (good). All other adjectives are regular and follow the same declension pattern depending on whether they end in a consonant, vowel, or nasal vowel.

example declension of shaun - "beautiful"
Positive Comparative Superlative
Nominative shaun shauny shaunist
Dative shauna shaunajo shaunasto
Genitive shaunas shaunaszo shaunashto

Nasal vowels retain their unnasalized variant in all declensions but the nominative-accusative comparative.

example declension of grautą - "great"
Positive Comparative Superlative
Nominative grautą grauter grautan
Dative grauta grauta grautast
Genitive grautas grautaszo grautaszan
