Shawafian

Shawafian is a language isolate* spoken by roughly 31% of the creatures of Shawaf, a loose confederacy of nations/groups that was in very close proximity to the Empire of Yageeb.

The language has a wide range of moods/aspects, unlike most other Pencilcosmos languages, and lacks passive voice and tense.

* most likely; a theory suggests that Shawafian is related to other languages within the Pencilcosmos.

Shawafians have no larynx, nose, lips, or teeth, although they do have multiple mouths, allowing for large amounts of coarticulated sounds which would be impossible with a single mouth.

Classification and Dialects
Shawafian is relatively synthetic, and also extremely regular (even for The Pencil Language).

Writing System
Shawafian uses a modified version of the Pencil Language script.

Nouns
Nouns have 4 cases: agentive, patientive, allative, and ablative.

Allative and ablative cases are tied closer with the verb rather than the noun, and sometimes they can be detached from the noun. This is thought to be an influence from The Pencil Language.

Syntax
The language is head-initial, and does not have a fixed word order (due to a strict case system).
