I recently became aware that the oldest bridge in Paris, the Pont Neuf, actually means “the New Bridge” in French. I had always assumed it was “Bridge Nine,” as neuf is also the word for nine. Why are nine and new so closely related? There doesn’t seem to be any obvious connection between the words.
In Spanish, new=nuevo/a and nine=nueve. In Italian, new=nuovo/a and nine=nove. Is this a case of convergent evolution, or do new and nine come from the same word?
I don’t think they have any relationship, they just sounded similar to begin with for the simple reason that there’s only so many combinations of consonants and vowels that you can make. If you have similar starting positions and fairly homogeneous ways of transforming words over time, you’re going to end up with the same result eventually.
To be fair, neither of the two posts preceding this one by you actually suggest that there is any convergence; both suggest that it is a fluke and that they were alike all along, although neither backs it up with a nice cite like **RadicalPi **did.
Such a connection has been seriously proposed, for example by the mathematician Karl Menninger in “Number Words and Number Symbols: A Cultural History of Numbers”.
