[Knobbly] It's a system the French use for wines which ensures that only wine made in a particular place (or in a particular way) can bear a particular name. The most famous example is Champagne.
[Tuj] I would automatically say Toozh, although there's a vague sense in my head that it could be a to-eye (but not quite like that, sort of using the Russian "bI" sound, where the "j" implies palatisation.
[flerdle] You talk funny? This is how I pronounce "Tuj". (Sorry about the format. I tried converting it to mp3 but then it turned into scratchy silence.)
[Rosie] As in Spotty Herbert? Not Herbert but yes to the arbitrary. If you sift some of the conversations we've had about name anagramming I'm sure you could find what it is.
(Tuj) There's a difference between being a herbert and being a Herbert. Fain would I suggest you were the former, or now, the latter, even. Where are these conversations? Are they in Another Place, or Mc-Eye-oss, as I call it?
