I've been hearing 'kewl' for a long time excessively on social media (mostly used by Americans). I wondered what accent it came from. I searched, but only found the following information about it:
- Kewl - /kjuːl/ (adjective): non-standard spelling of cool (fashionably attractive or impressive)
Origin: 1990s representing an affected or exaggerated pronunciation of cool - Lexico
- Generally restricted to the colloquial meaning of popular, and therefore this spelling is useful to distinguish this word from the standard meaning of cool. With this particular meaning it has been adopted into other languages - Wikitionary
I also searched vowels in American accents and dialects, but didn't find any helpful information.
So what accent did it originate from? Is there any accent which turns /uː/ to /juː/?
