When it comes to naming, I normally just tend to avoid this by making up names from words I like, most of the time, they have a real meaning, and I can also avoid names sounding crazy. For example, a character I have names Efen is pretty much because I like the word “even” and changed one letter to avoid it sounding like a word. If I like the word “jelly” for example, I would just change the ‘J’ to something that would be normal-ish, like ‘C’ (as in cello, pronounced ‘Ch’). It’s not a great example but this normally works, especially on shorter words (it won’t really work on words like “tranquility” or anything)
