Phonology
Molbi has a simple phonological inventory, with a total of 14 consonants and 5 vowels, plus diphthongs.

Consonants

 * Except for in deliberate speech, /h/ disappears when in the intervocalic position. Despite this, it remains written as if it were pronounced.
 * /s/ is realized as /z/ in the intervocalic position, but is always written as s.

Vowels

 * The possible diphthongs are /aj/, /oj/, /aw/, and /ew/.
 * When unstressed, /a/ tends to become [ɐ], and /e/ becomes [ɛ]. However, they are still written as a and e, respectively.

Orthography
Almost all phonemes in Molbi are written the same as they are in IPA. The two exceptions are: /ɾ/ is written as r, and /j/ is written as y.

Stress
Stress regularly falls on the second-to-last syllable.

Phonotactics
The syllable structure of Molbi is (C)V(l, m, n, r.)

Word Order
Molbi is a typologically harmonious SVO language. The basic word order is subject-verb-object, all noun modifiers (including adjectives, genitives, relative clauses, etc.) follow the noun, there are prepositions, and there is no case marking, which all are traits of consistently VO languages.

Nouns
Nouns are declined by their number, but not case.

Number
Number is not required to be marked in Molbi, and is frequently omitted, especially when context makes a noun's number clear. However, marking number with a suffix is still not uncommon.

The following table again uses miru (sky) as an example.

Verbs
Verbs are the most complex part of Molbi's grammar. They are conjugated by tense, aspect, voice, and mood, and use a variety of independently functioning affixes.

It is important to know that adjectives are a type of verb in Molbi and conjugate like all other verbs.

This table shows the order in which the conjugation affixes are used:

Tense
Molbi's tense system is rather unusual in that it makes use of not just 3 tenses (like many languages), but instead, 5 - in addition to the past, present, and future tense, Molbi has a 'remote past' tense and 'remote future' tense. It is up to the speaker how far in the past and future is far enough to use a remote tense.

The following table uses the verb root sem (to see) as an example.

Aspect
Molbi uses imperfective, perfective, perfect, and habitual aspect.

The following table uses the verb root sem (to see) as an example. Note that none of these specify tense at all; for example, the imperfective marks an ongoing event, which could be occuring in the past, present, or future.

Voice
The -toy suffix makes a verb passive.

Mood, Causative, and Negative Forms
Molbi has a total of seven moods, in addition to a causative and negative form, all of which are often used alongside tense and aspect affixes.

The following table uses the verb root sem (to see) as an example. If multiple of these forms are used, their suffixes should come in the order given in this table.

The interrogative suffix and intonation are the sole markers of a question in Molbi; word order does not change.

Non-Finite Verb Forms
In Molbi, verbs become gerunds with the prefix ni-, participles with the prefix we-, and adverbs with the prefix gu-. Adjectives that directly modify nouns must use the we- prefix because adjectives are considered to be a type of verb in Molbi.

Personal Pronouns
Personal pronouns are dropped very frequently when implied.

To form a reflexive pronoun, the plain pronoun is reduplicated, besides the number suffix. So the reflexive of me is meme, but the reflexive of poya is popoya.

Correlative Pronouns

 * The query and indefinite pronouns are the same, meaning words like "who" and "someone" both are covered by the word lome.
 * Often, when referring to people, lewo  'person' is omitted. So Molbi speakers would say "every is staring" instead of "everyone is staring."
 * The words in the thing column (besides the query word) are also used as adjectives; so be could mean "this thing", or "this (as an adjective.)"
 * Nayn is not only used as a correlative pronoun. It is used as the negative mood suffix, as the word 'not', for an answer 'no', as an interjection, etc.
 * The words in the way column (besides the query word) function as verbs. They often become adverbs with the gu- prefix.
 * Yusom bere and yusom mare literally translate to because this way, because that way, and are used as "because" and "so" respectively, but only when connecting two sentences.

Numbers
Molbi's number system is base ten. Numbers are formed through a very regular process: Ordinals (first, second...) are formed with the gu- prefix, frequency words by adding the word bi  'time' after the number, and multiples by adding dum bi  'more time' after the number.
 * 336 > three hundreds, three tens, and six
 * 21216 > two ten thousands, ten and two hundreds, one ten, and six

Fractions are formed by saying the numerator, then the word 'of', then the denominator. For example, one sixth would be said 'one of six'.

Here are the most commonly used numbers of Molbi:

Comparatives
Comparatives are formed with the verb melo and either dum  'more', yum  'less', or mim  'as'.

Comparative phrases have the order of subject, ' dum/yum/mim ', the comparative adjective, 'melo ', then, what is being compared to the subject. For example:

Sa dum til melo po = you more tall than he = you are taller than him.

Superlatives are formed by adding the word sel 'most' before the verb.

Sa sel til = you most tall = you are the tallest.

Relative Clauses
Relative clauses are not marked with subordinators in Molbi. Instead, the verb in the clause is converted to an adjective with the prefix we-. Relative clauses, like all modifiers in Molbi, follow the noun.
