This is intended to be a large tutorial that becomes increasingly complex. Once you've mastered this, you've mastered most of Brevlo.


Compound Vowels

Compound vowels (aka "diphthongs") are just two or more vowels that form a complete sound. In Brevlo these are:

Compound Consonants

Compound consonants (aka "digraphs") are just two or more consonants that sort of naturally "blend together" to form a complete sound.

Parts of Speech



Adjectives, Adverbs, and Articles





Keywords are Brevlo's answer to prepositions and conjunctions. They always end in "e" and are terminated with "ce".


Inquisitors (Interrogatives)

Much of Brevlo's strength comes from the way it handles inquisition. Any Brevlo word can be made into an "inquisitor" which is just a word that specifies a question.


Structuring words

Structuring words are single-syllable words that start with "c". They are the only words that start with "c" in Brevlo. They can be left off the end of a sentence.

Example Sentences

Basic Numbers

Brevlo numbers are joined by z to form complete numbers.

These numbers can be combined to form other numbers.

Noun vs. Adjective Numbers

The noun form ends in "o" but the adjective form of numbers end in "a". Writing 77, for example, would be vavozvavo, but writing "77 dogs" would be hundo vavazvava — of course you could just use the number.

Grouping Nouns and Phrases

Nouns and phrases can be grouped with keywords. The grouping helps a listener or reader know when a keyword phrase (or "prepositional" phrase) ends. Note: ce can be left off the end of a sentence, as a period (.) terminates all open keywords.

Verbs and Keywords

In English, people can be confused by phrases such as "I'm driving Bill from Alabama." Does that mean that Bill is from Alabama, or that I'm driving Bill and I'm driving from Alabama? Brevlo handles this easily.

Advanced Verbs

Even though Brevlo verbs are relatively easy (this includes the comparison to other constructed languages like Esperanto) you should spend a decent amount of time reading over the examples.

Adverbs to Modify Tense

Brevlo does not modify the verb to change tense. In fact, tense is entirely optional with Brevlo if a time indicator is specified. For example, in English we might say "I will run tomorrow", but in Brevlo you could just as easily say "I run tomorrow".

The most common tense-manipulating adverbs are the following:

"runu" Tense Example

Joining Verbs

Verbs can be grouped within keywords for the purpose of reusing the subject or object.


Imperative verbs (also known as "command" verbs) are treated exactly the same way as normal verbs, but are wrapped in an attitude indicator. The attitude indicators are special classes of words that will be covered later. For now, just know that commands will be trivial.


Infinitives are verbs that are often prefixed with "to" in English. Examples include "I like to run" with "to run" being the infinitive. In Brevlo, there are three distinct ways to think about infinitives.

Warning: infinitives can seem complicated when you're used to a language like English.


The keyword dose indicates that the subject on the left does the action following dose. It places the subject at the beginning of the keyword phrase started by dose.


The keyword rese is just like dose except that it uses the passive version, and places the subject on the left at the end of the keyword phrase started by rese.


The keyword nake indicates the "act" of something.

Common Issues

Why do we say mivo vantu cu nake vuvo draivu cu mivo instead of mivo vantu cu vuvo dose draivu cu mivo? ("I want the act of you driving me" instead of "I want you to drive me").

The first one specifies that you're solely interested in the act of being driven. The second one says "I want you (who does the act of driving me)". Either one can be correct depending on context. Just remember, if you're trying to specify the act of something then use nake.

Adjective Grouping

Adjectives, articles, and adverbs (A-words) can be grouped with ca. Grouping allows one to specify the exact order that A-words are applied to a noun.

Why Group A-Words?

Take the following sentence:

That can be interpreted a few different ways:

Brevlo fixes this by having a built-in order for A-words.
