Correct spelling for the English word "fewell" is [fjˈuːɛl], [fjˈuːɛl], [f_j_ˈuː_ɛ_l] (IPA phonetic alphabet).
The word "fewell" has an interesting etymology. It comes from Middle English "fuewelle" or "fwele", which originated from Old English "fēow(e)l" or "fȳ(e)l". These Old English forms, in turn, can be traced back to the Proto-Germanic word "*fōilaz" or "*fōlaz". This Proto-Germanic root had the basic meaning of "fuel" or "combustible material". It is related to the Old Norse word "fjǫl", meaning "fuel", and the Old High German word "fuel", meaning "tinder" or "spindle". Over time, "fewell" underwent various spelling changes before settling on its current form, "fuel".
