On: Did English ever have a formal version of “you”?

[jjtheblunt]

It was eth (voiced th), not thorn (unvoiced th). But I was _very_happy_ to see someone else knew this.

The glyph for Eth looks like delta (as in calculus) with an extra cross atop it, so, distorted, looks very much like a script y.

You can see at least thorn still in use in Icelandic, by the way.
