Ugh! 'Pirl', 'pirl'! What a nasty tinny sort of word. But I do wonder how much of the similarity they're talking about here is accounted by phonoaesthetics, and how much of it might be simply due to some inevitable coincidence (like Zipf's law being applicable to gibberish texts). I mean, common concepts seem more likely to be referred to by short words, and there are only so many short words that can be formed with a given number of phonemes. Shouldn't some repetition and similarity be expected from that alone?
