All that stuff on Merlin in the Character Clinic has sparked a plot bunny. I'm no good with the origins or meanings of words, so I thought I'd ask here. Basically, what are the origins of the word 'Muggle'? Does it mean anything, or is it a word that JKR simply made up?
Do people think that the word has been used for non-magical people since there have been wizards to distinguish themselves? If not, what word or phrase might have been used instead? For example, would Merlin and Morgana call people Muggles?
Greatful for any help.
