Quiet! Letters at work.

Very interesting, Proof. I thought it funny that some have been added because of pretentiousness.

I have been unable to find out exactly how wr was pronounced in words like wring and write.

Old English had other unusual combinations like *hlahhian "laugh", hnutu "nut", and hwa "who". These were probably voiceless /l/, /n/, and /w/.

But there were also wr as in wringan "wring" and wl as in wlanc "pride". How were they pronounced?

try posting a query to David Crystal. He's pretty good on that kind of thing.

Or - Quinion? I don't know about David Crystal, but Quinion always answers and does a good bit of research.
