but what have we learned from all of this?

That ad hoc pronunciation based on English spelling are worse than the English spelling system itself. No wait, I already knew that.

That the pronunciation of approximant consonants (link) is a complicated affair. No wait, I already knew that.

I guess I've learned nothing from this thread, but it has reinforced my awe in the face of all facets of language. No wait, you all knew that already.

Ceci n'est pas un seing.
