The MaCuSi is a minimalist ideolanguage in terms of phonology and grammar, but not lexically. Indeed, many constructed languages are centered around a single theme. The MaCuSi was designed to allow the generation of all the words of a language.

Phonologically, the MaCuSi uses seventeen consonants (b, c, d, f, g, j, l, m, n, p, r, s, t, v, w, x, z) and five vowels (a, e, i, o, u). A syllable consists of a consonant written in uppercase followed by a vowel written in lowercase. The pronunciation of this syllable leaves no room for sound ambiguity.

The principle of the MaCuSi is to have only 85 words. With the arrangement of these 85 words, it is theoretically possible to generate over 377 billion different words with one to six syllables. The general idea is not to have to learn anything other than the 85 basic words but to understand or discover the possible and logical combinations, to push the limits of language to serve as a means of communication between speakers of different languages.

From a grammatical point of view, the MaCuSi aims to keep only what is essential and is characterized by a lack of conjugation, gender for nouns, complicated rules, exceptions, particles, etc.


The first, and not least, advantage of this language is that you only need to learn the 85 vocabulary words. This allows you to learn the language in just two days.

The second advantage of this language is that it retains the modern Latin alphabet, which is known by over 70% of the world's population. Indeed, many invented languages use a new alphabet that either includes too many signs or has a non-obvious logic.

The third advantage is that you can use MaCuSi from any language that uses the modern Latin alphabet. You just need to have the translation of the 85 basic words and switch to Subject - Verb - Complement construction for languages that do not use this type of construction.

Writing System

Each of the 85 words consists of a consonant written in uppercase followed by a vowel written in lowercase. Example: Ba, Ce, Di, Fo, Gu...


There are no real constraints on how to pronounce the sounds. Bu can be pronounced Bu or Bou... Be can be pronounced Be or Bé. Since there are only 22 phonemes, there is no risk of confusion in pronunciation.

In Summary
