Of the 500 words in this list, 287 can be used as a noun, including into, individual, interest, international, increase. Plenty of words do more than one job: state is a noun, a verb and an adjective depending on how you use it, which is why these numbers add up to more than the list itself.
How this list is built
The words come from the Datamuse language API, then get cleaned up, because the raw output is not much use on its own. Each word is checked against an English dictionary, with a frequency floor for anything not in it, so ordinary inflections survive while noise does not. Roman numerals, fragments and vowel-less abbreviations are stripped out.
What is left is ranked by how often each word actually appears in written English. That ordering is the point: it puts the words you might actually want at the top. The full method is on how we build these.
