The Soyombo script was the first Mongolian script to be written horizontally from left to right, in contrast to earlier scripts that had been written vertically. As in the Tibetan and Devanagari scripts, the signs are suspended below a horizontal line, giving each line of text a visible "backbone".

The two variations of the ''Soyombo'' symbol are used as special characters to mark the start and end of a text. Two of its elements (the upper triangle and the right vertical bar) form the angular base frame for the other characters.

Within this frame, the syllables are composed of one to three elements. The first [[consonant]] is placed high within the angle.
The [[vowel]] is given by a mark above the frame, except for u and ü which are marked in the low center.
A second consonant is specified by a small mark, appended to the inside of the vertical bar, pushing any u or ü mark to the left side.
A short oblique hook at the bottom of the vertical bar marks a long vowel.
There is also a curved or jagged mark to the right of the vertical bar for the two [[diphthong]]s.
