I’m not a native English speaker and I don’t speak French either, but something I’ve always found interesting when searching the Violette name is that it’s pronounced differently from the American English “Violet.”
So I have this headcanon that other students mispronounced her name a lot during the first few months after she arrived at Hogwarts. And since she was born in London, she was probably already used to people saying her name incorrectly. After correcting them once or twice, she would just give up and assume people were calling her whenever they said something close enough.
“Well… my name is actually pronounced Vee-oh-LET, if you really care.” 😅
By the way, I’m not sure if this headcanon is actually accurate haha, cuz I’m not British I haven't traveled to Europe for once. I wonder how British people pronounce “Violette" btw 🤔
