The Marchen scripts has some similarities with the
Tibetan scripts and
Lantsa but at the same time differs considerably from these. It also differs from other writing systems in the
Bon tradition, such as Marchung, Pungchen, Pungchung and Drusha. A feature the Marchen script shares with Tibetan script and Lantsa are the special subjoined variants of the letters
wa,
ya and
ra. The vowel diacritics are most similar to those of Drusha. A distinguishing feature of the Marchen script is the presence of a left-facing
swastika, a symbol of the Bon religion, which is used both to write the letter
nya and as a punctuation mark. The Marchen script consists of 30 consonant letters, four vowel diacritics, a vowel length marker
-a and two diacritics for nasalization (corresponding to
candrabindu and
anusvara). Each consonant has an accompanying vowel
a which can be modified with the four vowel diacritics. Consonant clusters are written just like in Tibetan script by stacking two or more consonants on top of each other vertically. Just as in Tibetan script, there are simplified forms for medial
w,
y and
r. However, there is no simplified form of initial
r. Unlike in Tibetan script, there is no sign to mark syllable boundaries, which means that ambiguities can sometimes arise. The Marchen script can be written in two different styles: one with thick angular letters and one with thin rounded ones. ==Alphabet==
