Uproimous

General Information
Uproimous (/ʊprɔ́ɪmʊs/, natively ‘Upróiméus) is an Otsyeupsyup language spoken in the tropics on the western coast of the largest continent on the planet Patrona, in the country Belsha, a very linguistically diverse and successful country.

Consonants

 * Labialization among the nasals and stops is only distinguished before unrounded vowels.

Vowels

 * There are only two diphthongs: /eu/ and /oi/

Phonotactics
CV(F), N
 * C can be any lone consonant or a consonant cluster.
 * The allowed syllable-initial clusters are: /pr/, /pj/, /tr/, /tj/, /kr/, /kj/, /sr/, and /sj/.
 * The allowed coda consonants are /n/, /p/, /t/, /k/, /s/, and /r/.
 * Coda /n/ changes to match the place of articulation of any following consonant.
 * Coda stops are not allowed before other stops.
 * Coda /r/ cannot occur after a diphthong.
 * The sequences /ji/ and /wu/ are not allowed, and become /ri/ and /ru/ if they should arise.

Tone
All words must start as low or high tone, and that pitch will carry through the whole word unless the word contains an accent on any non-initial syllable, where the tone of all vowels on and after the accent switch to the opposite tone. There can only be one accent in a word.

For example, LLL /kàlàlò/, HHH /káláló/, and HLL /kálàlò/ are all allowed, but LHL /kàlálò/ is not, as that would require two pitch changes (in bold).

Verbs
Verbs are very expressive in all Otsyeupsyup languages, and Uproimous is no exception. Verbs conjugate for person and number of the subject, direct object, and indirect object, can undergo many changes in valency, are grammatically marked for formality, and are conjugated for tense, aspect, and evidentiality.

Syntax
SOV
