Word derivation for "twelve" :
Basque = hamabi (from ten + two)
Finnish = kaksitoista (two + -teen)
Miresua = bakitaima (two + -teen)
This is a new word. Now I've remembered why I didn't make numbers above 10 before. My number naming scheme looks like it will run into issues with eighteen and nineteen.
The word twelve occurs four times in Alice's Adventures in Wonderland.
"And that's the jury-box," thought Alice, "and those twelve creatures," (she was obliged to say "creatures," you see, because some of them were animals, and some were birds,) "I suppose they are the jurors."
