Orokin Language

The Orokin Language is largely based upon English but apparently also contains extra characters for certain phonemes including diphthongs ("io") and digraphs ("th" and "sh"). The characters are diagonally slanted and are written left to right. Vowels take the form of polarity symbols written above the regular characters. There is frequent variation in both the direction of writing as well as the vertical orientation though this variation is likely an artifact of texture placement.

Although there are no live excerpts of the Orokin Language to demonstrate how it is spoken, the Lotus, Ordis, Tenno and the Red Veil presumably understand and can speak Orokin.

Orokin alphabet
Adding a small dash to a character often functions like an "h" behind the letter. For example, adding a dash to the characters for "P", "S" and "T" produce "PH", "SH" and "TH" sounds, respectively.

The Vazarin and Naramon polarities are used as characters on one particular piece of text on Trinity's mask and on Excalibur. However, their associated phonemes (if any) are currently unknown.
