Matoran Alphabet

The Matoran Alphabet was the system of written language used mainly by Matoran and several other inhabitants of the Bionicle. It is similar in most respects to our own, using a system of circles, dots, and lines to convey the characters the Latin alphabet.

On Voya Nui and possibly Mahri Nui (given they were once connected) hexagons were used in place of circles and it was a different version of K which looked more like the latin letter. However, it is unknown if this is merely a cosmetic change, or practical.

Here is the guide:

Trivia
