The word "Aire" seems to be associated with music, but I haven't been able to track down exactly why. There is a river called Aire in England, and it apparently comes from the Celtic meaning "strongly flowing", and "Aire" seems to be part of the name of groups that play Celtic music, and also in other various music groups (barbershop, G&S).
I'm not sure if it's supposed to be a particular style of music, something that is "strongly flowing", perhaps, or if it's just some word that's associated with music, so it gets used.
Anyway, I haven't been able to find it anywhere not capitalized, so I'm pretty sure it's not a legal Boggle word.
Anyone have any better ideas/sources on this word?
