How could English give up such lovely letters? Especially þ, which sounds like the English “th.” We totally need a separate letter for that sound. Having “th” represent it makes no sense, really. Plus, þ can trace its ancestry all the way back to runic alphabets. How cool is that?
I feel less nostalgia for the equally runic letter ƿ (wynn), though, perhaps because we have do have an acceptable substitution for that one. ƿ has been dropped by all modern alphabets, I believe; an unfair bias on all our parts, no doubt, but there it is. 🙂
