Yes, each generation has words or a style of typing that they grew up or had to adapt to.

IIRC Boomers and Gen Z use more emoji than Gen X and Y.

Millenials grew up with keyboards, so they tend to type full sentences, punctuation, shit like that. With Gen X being a toss-up.

Boomers tend to use formal language, but they suck at distilling their thoughts into something another human person can understand. (Boomer ramblings on Facebook)

Wish I could find the article that broke it down, but search engine sludge makes any question about generations into links to quizzes.
