I didn’t realise the name “unicycle” was so obscure… people seem to like calling it all manner of things. If I had a pound for each time someone called it a monocycle, I’d have about £4.
The best one was where a little kid got the name right, but the parent didn’t…
Sadly they didn’t burst out into song. Does that mean I’m not living in a dream world after all?
Unicycle is a Frankenstein kind of word like hexadecimal. The root kyklo is Greek and the prefix uni is Latin. In the case of hexadecimal the root decem is Latin and the prefix hexa is Greek. Monocycle is probably a more appropriate word but we English speakers reserve that for a large wheel in which the pedaller occupies the center.
