One that bugs me a lot that I noticed just in the last 5 years or so is over pronouncing the T in words like celebrity and community - yes it’s spelled with a T but it’s not fully voiced like you’re saying the word Tea. I noticed it first on YouTube and now in some audiobooks and even the occasional coworker.
I would be happy for it to switch places with Chartreuse, which feels strongly like a red word and is definitely not a bright yellow-green
