I know that varies by region, but schoolchildren are generally taught cursive as a faster way to write. It already requires some memorisation with some glyphs being different from block letters. Why not make an additional step and completely replace it with shorthand, making writing an order of magnitude faster?
I googled it… and it’s just the American word for “joined-up writing”, like you do in primary school.
It’s literally just that. All those whingeing posts on social media… they were crying about joined-up writing. Hahahahaha. What an insane bunch of babies.
[Edit] when I say “googled”, I of course mean I googled it with duckduckgo, or duckduckgoed it or whatever.
