Yoylese

Description and History
Yoylese is an endangered language that was created via the mass borrowing of the English Lexicon into the phonological system of Old Yoylese. Its name, setting, and writing system come from Yoyleland, a fictional region in the web-series Battle for Dream Island.

Yoylese was a single language with little dialectal variation due to the clustering of people within the capital up until the arrival of English settlers into Yoyleland. This caused the capital city of Yoyle City and costal areas to branch off from Old Yoylese into their own English-influenced language now referred to by the original name of the language. Old Yoylese is now spoken only in the inland countryside of Yoyleland. Also during this period, a sound shift occurred causing the sounds /β/ and /ɣ/ to become /v/ and /h/ respectively due to English influence on the language. This sound change did not happen in Old Yoylese.

Phonotactics
Syllables follow the (C)V(C) structure with no diagraphs.

The only diphthong allowed is /oi/

Writing System
The writing system differs from the one seen in BFDI in that letters represent different sounds to create a more featural system, and to prevent a 1-1 replica of English orthography.
