Now, I know what you’re going to tell me... there’s no such thing as South Germanic!
Since there is already an East, West, and North branch of the germanic language family, the missing South branch is reserved for my germanic constructed language project, which has gone through many names, and will probably go through a few more, but which for the moment is called Theadish or Northeadish (Nurðþþȳðesc). It was just plain old Theadish until I discovered that there are about six unique constructed germanic languages called Theadish out there, with varying degrees of originality and complexity.
There are also a couple of spin-offs, such as Þiydʒ, which is really a lot more west-germanicky than its Northeadish cousin, and Ōstþȳðesk, which is really just Northeadish with a different gothic-like alphabet, and i’ve envisioned, as i’ve worked on it over the years, maybe a bit of a “slavic” accent.
I’m not particularly one of those “conlangers” who goes out and tries to create a history and a world and a universe for their speakers to live in; really i just love germanic languages and this is my attempt to roll up all the things i love about them into one big pot, and where conflicts occur, so do dialects like Þiydʒ. For example, i love not using any sort of postalveolar fricatives in Northeadish (e.g. fish = fesc [fɛsk]) – after the Proto-germanic (fiskaz), Gothic (fisks), and Old Norse (fiskr) model – but at the same time, I love that West Germanic uses them in spades (fish, Fisch), so Þiydʒ has lots of them (fec [fɛʃ]).
