My blogging on #EastNorse has not been terribly regular (see thread above) but here I go with a theme that I work on:
I sifted the whole Old Swedish known vocabulary for words where correlates of (Late) Old (West) Norse (=ON) <jǫ> occur.
They are very diverse and include:
iæ(>jä) (commonest)
ia (in some older texts/in some words), becomes iæ
iø(>jö)
io (which becomes iø>jö in later Swedish)
io (which stays as jo in later Swedish)
iō (before rdh/rt)
iu
Whence this stunning diversity? 👇🏻
