Are there any English words that contain a number or symbol? (excluding hyphenated words) [duplicate]
Solution 1:
To answer this question, you might find a word list file (these files are used by programmers for things like spell checking, text parsing, writing scrabble AIs, etc) and doing a search for numbers and symbols.
Start by doing a google search of "word list file" and then doing a ctrl+f search inside those files.
Here is an example, but it doesn't contain any words with numbers or symbols.
Here is another, and it contains "&c" and words like 1st, 2nd, 3rd, 4th, etc.
Here is an interactive tool that allows you to generate your own word list files.
From my research, I can't find any words that contain numbers or symbols other than obvious ones (1st, 2nd, 3rd...) and &c, which vynsane already pointed out is a result of &'s older meaning.
