      An em dash is --, two dashes. It’s a way to break up a sentence – sort of like a comma.

      Apparently AI uses them a lot.

        I’m too pedantic to let this slide. An em-dash — is a single dash, the width of an m. An en-dash – is a single dash the width of an n

          If we’re going to be pedantic, the em is a unit of width that depends on the font, but not necessarily the with off an m. Some texts apparently used to define it as the width of the capital M, but this definition is obsolete. source

          On that note, are em dashes and en dashes identical in monospace fonts, if every letter is the same width?

          Edit: I tested this on a few monospace fonts, and they have a character for en dashes but not em dashes

            Very, very similar, yes. It can be annoying!

            We’ve got our browser set to use a monospace font for everything, everywhere, including all websites. It’s awesome for seeing if you’ve accidentally typed two spaces. Not so great for checking to make sure you’re using the right kind of dash!

            (also Lemmy, because it’s annoying, is going to turn my double - here into an en/em dash (not 100% sure which). In this case, I DO in fact mean a double -, dangit.)

          So that’s where the name comes from. I never would’ve guessed it was something this straightforward :)

        I don’t use AI much. Is it actually using two dashes? 'Cause an em dash is its own character: “—” vs --

        I had to put those in manually with the — html entity in the pre utf-8 web days.

          You’re right. I’ve always just typed two hyphens and called it good but technically it should be one long dash.

            Haha, yeah, I probably wouldn’t have learned to care that much if design clients didn’t yell at me about it 20 years ago.

          Different length dashes serve different grammatical purposes, so you can assume they didn’t just use one dash because they intended to use two.

          Funnily enough, the “dash” people use most often isn’t even technically called a dash, it’s a hyphen.
