Nouns
There are 20 grammatical noun cases: nominative, accusative, genitive, dative, vocative, comitative, instrumental, partitive, inessive, elative, delative, illative, prolative, terminative, adessive, ablative, allative, essive, limitative, and temporal. There are four grammatical numbers: singular, dual, trial, and plural. There is also something called the "grammatical stem". It functions as the grammatical gender for animate nouns, but for inanimate/abstract nouns, it represents a more specific meaning. Since all of these decline, this totals to 240 declensions.

Noun Morphology
This is the structure of nouns.

Firstly, we need to figure out what those two vowels are. Otřlaň has vowel harmony, and the two vowels are decided based on the vowel group of the root word. There are two vowel groups:

The vowel ⟨a⟩ is neutral. A root word belongs to a certain vowel group if all of its vowels are either from that group or are ⟨a⟩.

If the root word is group 1, then Vowel 1 and Vowel 2 are ⟨e⟩ and ⟨i⟩. If it is group 2, then they are ⟨o⟩ and ⟨u⟩

Here is the Number + Stem ([v1] means Vowel 1).

* For the Dual and Trial Stem 3 suffixes, [v1] is added to the end if there are no suffixes following it.

Now, the cases ([v2] means vowel 2).

Now, here are all the suffixes that can be added to a noun:

Verbs
Otřlaň has three voices: active, passive and reflexive. The reflexive voice is the subject of the sentence is the same as the object, e.g. “I hurt myself.” It has five moods: indicative, imperative, interrogative, exclamatory, and subjunctive. It also has four tenses: past, present, future, future-in-the-past, and they each have four aspects: simple, perfect, continuous, and perfect continuous. This totals to 240 conjugations.

Verb Morphology
* an 'a' is added to the end of a verb if it does not have any suffixes

The vowel system is the same as the nouns. Also, there is only one prefix 'n[v1]-', which turns the verb into its antonym (e.g. fita = to live, nefita = to die). Here is the chart for Voice + Mood.

Now Tense + Aspect.

Here are the suffixes:

Adjectives
Adjectives are simpler than the previous two. Adjectives go before the noun. The prefix n[v1]- turns an adjective into its antonym. The prefix [v1]t[v1]- turns an adjective into its comparative form. The prefix nam[v1]- turns and adjective into its superlative form. The suffix -a turns it into the verb form, "to be ADJECTIVE" and the suffix -aň turns it into a noun "state of being ADJECTIVE".
