San'Shyuum language

The language of the San'Shyuum is similar to Medieval Gregorian-style chanting, based on religious sermons by the High Prophet of Regret on Installation 05. Whether this is spoken by all San'Shyuum, or if it is a special dialect for religious purposes is unknown.

The San'Shyuum also used non-verbal communication, in the form of elaborate or simple hand gestures, though some involved movement of the head. Most other races, such as the Sangheili, were completely unaware of this. The San'Shyuum were also able to convey expressions through these gestures, such as satisfaction, irony, obeisance, amusement, respect, and empathy. An extra flip of the thumb was used to show a gesture was being used mockingly. Accents could also be conveyed through these gestures. The Stoics on Janjur Qom seemed to have used the same hand gestures.
