katlaughing - I never said you or your opinions were stupid, very sorry if you tok my comments that way, no harm at all intended. I just wanted to be clear to others in my assertion that there is absolutely no cultural connection between aboriginal didgeridoos and any sort of Irish or Scottish bog horn ever found. The fact that somebody makes a replica of one of these bog artifacts and decides it CAN be played as a didgeridoo, does not IN ANY WAY mean that it WAS played like a didgeridoo. It is entirely possible that mouthpieces were fashioned of another material, say wood, perhaps, or that there are/were other bits to these instruments that have not survived, or that they were ceremonial offerings, made to look like instruments but not actually playable, or that they were mouthed in some way like a didgeridoo, but does that mean they actually were part of any musical performance? for dancing? doubt it. more likely a horn like this would have been a war trumpet of some kind, designed to produce a rather loud and terrifying sound, not likely to be used for rythmic droning. Though I suppose some argument could be made that a score or so of these all going together as didgeridoos might have sounded pretty loud and eerie to an enemy force. The fact is, right now we just don't know, it is all conjecture, and we may never know for certain what exactly the function of these bog instruments were in the culture that produced them.

As to the initial post, I say there is a possibility that the term comes from the Irish, haven't read the dissertation, but I would expect it attempts to describe when the first Irish speaking colonists arrived in Australia, and where, and where they dispersed too, and when the first use of the word didgeridoo appears in Australian English usage. It is not an aboriginal word or expression. Even having demonstrated all of this, it is still conjecture on her part, and perhaps just another cod-etymology attempted by someone who stumbles on the apparent similarites of sounds between languages and tries to make a connection that was never there. Interesting discussion though.
