Razor is more popular than "cursed" (ranked 12,298) and not as popular as "specifying" (12,296). That's according to Wordcount.org
WordCount is an artistic experiment in the way we use language. It presents the 86,800 most frequently used English words, ranked in order of commonness. Each word is scaled to reflect its frequency relative to the words that precede and follow it, giving a visual barometer of relevance. The larger the word, the more we use it. The smaller the word, the more uncommon it is.
It's lots of fun to look up words and see what's "before" and "after" it. For example, the word before "imagination" is "formula"... and "brake" is just after "hillside" ... and "dog" (1,279) is way more popular than "cat" (2,532) which interestingly is the word right after "bird".
