Vowels in Manakahthey play different roles. Depending on what “action” you need. Vowels communicate a type of action. If you don’t know what kind of action a vowel sound is communicating in order to read the symbols. Modern Hebrew doesn’t teach this information. This seems like a secret among only language experts or maybe to their credit they just don’t know.
The Vowel Letters of Manakahthey are …
“𐤄” aHBaL – this is the “air” sign. This vowel as “air” to words. This communicates power of air. That air sign is natural and stable. It communicates life but not strong movement. It is as the energy of walking or moving.
“𐤅” uu – this is the connection symbol. It adds electricity to words. This communicates the power of energy. This is as the energy of jumping, running or magnetism.
& sometimes “𐤉” YeD – when this symbol is used as a vowel, it is located in the middle or end of words. It adds “manual” control being the “hand” sign, it’s easy to understand. It is energy, but not as strong as 𐤅 which is electrical, but more than the 𐤄 which is air. 𐤉 gives words that “push” motivation. This is as the energy of moving by manual pushing, pulling or controlling etc.
In my book, Primitive Sign Language, I wrote about fascinating relationship that these letters (𐤄 ,𐤅,𐤉). It’s not complicated and there are no need for vowel marks. As time goes by, I will introduce many words and you can learn the relationships of these vowel symbols.
Alternatively, you can support my efforts and find out how these letters are used in Manakahthey and buy a copy of Primitive Sign Language.
