The Gith Alphabet
The gith use a written language composed of alphabetic symbols arranged in circular clusters called tir'su. Each "spoke" on the wheel corresponds to a letter of the alphabet. Each cluster of characters represents a single word, and multiple tir'su connect to form phrases and sentences.
Githyanki and githzerai both speak Gith, but each race has a distinct dialect and accent. Similarly, the two races of gith differentiate their language by how they write it. Githyanki write a tir'su clockwise, starting at the top. Githzerai use the same letter symbols but write their tir'su counterclockwise, starting from the bottom.
