Kite! Sometimes I’m out of ideas so I just pick random words I happen to be reading.
Any birders out there probably know that kite isn’t just something you fly at the end of a string but a kind of bird. Apparently the former was named after the latter when it came out in the seventeenth century because it hovers in the air like a bird. Why that particular bird, I don’t know.
Kite the bird comes from the Old English, and it’s thought to come from the sound the bird makes (don’t ask me how; it makes no sense to me). Interestingly enough (shut up, I think it’s interesting), “go fly a kite” comes from a song Bing Crosby sang. Just “fly a kite” is over a century older, appearing in 1805 meaning to “raise money by issuing commercial paper on nonexistent funds”, and it’s where we get check kiting from.
