This system is created in 1943 by Juan Antonio Carissimi Dominguez (Uruguayan). He’s a stenographer and uses Marti system. He kept from the latter the strokes for vowels.
He decided to use the division of words into syllables.
A syllable in Spanish can be formed by:
1) vowel(s) (ex.: Abarcar)
2) consonant + vowel(s) (ex.: BOca)
3) consonant + vowel(s) + consonant (ex.: BARco)
4) 1st consonant + 2nd consonant + vowel(s) + 3 rd consonant (ex.: BLANco)
Vowel(s) means just one vowel or a group of them.
In pattern #3, the 2nd consonant may be R / L / N / M / or S.
In pattern #4, the 2nd consonant may be R or L.
When other consonants (apart of R L N M S) are not fundamental must be deleted, example: oFtalmologo, aBstraCto, aDjuntar, etc.
In the case of the pattern #1, only one vowel must be written joined to the first consonant.
This system uses three position for vowels (from the top to the bottom):
2nd: E I
3rd: O U
The first vowel after a consonant indicates the position, for example: HIJO –> two syllables: I – JO.
JO indicates 3rd position. But HIJA –> I – JA (2nd)
