G'day again sorefingers,

Strictly, if you want TW that's something like feadog stain (I'm no Irish/Gealic speaker) ...

That "feadog" is cognate with most of the other Europeam words that give us "fife" in English - the "d" in feadog being more of a 'thorn' ... the old Germanic Runic / "th" consonant (mis)represented today by the "Y" in "Ye Olde ..." (Stain" (~ spelling?) is "tin" (cognate with Late Latin stannum). Whistles have been made from oat stalks, reeds, willow bark tubes, hollow bones ... or anything else that could be used as a cylinder that can be modified by a sinple knife blade.

Regards,

Bob Bolton
