Chaeingaiel

Chaeingaiel, also known as Galactic, is the most widely spoken language in the Milky Way Galaxy, and is considered the lingua franca of trade, politics, law, and everyday communication.

History
Chaeingaiel's exact origins are disputed; its origins are commonly traced to the Eqjejak-Tidn branch of the Luagjs language family, hailing from the Ouaios continent on the planet Miramac as long ago as 2m, which would make it the oldest known language still spoken. The influence of ancient Chaeingaiel's Eqjejak-Tidn siblings is still evident today: words such as zveung (mathematics), kyze (acid), and even the name Sheelki have been theorized as having origins in other languages. Chaeingaiel first appeared in an identifiable form in circa 2m250k in the Shenkheel Manuscript. Shenkheel, while unrecognizable to its modern counterpart and almost entirely lost to time, is modern Chaeingaiel's direct ancestor and can be understood somewhat effectively with only moderate interpretation. Notably missing from Shenkheel are the multitude of affixes by which modern Chaeingaiel can be immediately identified. Many of modern Chaingaiel's affixes had their origins in Shenkheel as full words, such as bie (of) becoming  'eb.
