Okay, this is seriously fucking with my head and I need to know if this is just an American thing--'Rozy' is wrong. Rozanna is just simply outright wrong, it's not how you spell Rosanna unless you're some white trash or nigger-tier reprobate who doesn't understand etymology. The contraction of Rozy is particularly egregious because absolutely no part of my brain wants to learn to pronounce it the stupid way Ralph wants to pretend you should say it, like when a black gets named Le-A and they swear it's LeDashA, even with his little Cozy Rozy rhyme.
I read 'Rozy' instinctively as 'R-ozzy', like the nickname 'Roz'. Rosanna is good, proper, makes sense and can easily be read phonetically without a second thought--Rozanna is not the same and phonetically does not work the way they're trying to use it. They functionally named their child Roz and they're too dumb to understand how to correctly pronounce it. Is the nickname 'Roz' too uncommon in the US for a distinction between 'Ros' and 'Roz' to exist? Is this nonsense just accepted without complaint in American English now? Am I the only one who doesn't have these pathways formed in my brain to go along with this charade of a name?
