Quick Q.: What were the 18 languages Wilfrid supposedly spoke? Sources?

[ReneZ]

I used to have a colleague who could speak about 10, and I can testify they were all almost unintelligible.
Probably his native Swedish was very good, but I had no way to tell.

Alain Touwaide has 12, and those I overheard were ptetty clear.

All OT of course...
