What website will give me the frequency of a word in the English language?

Solution 1:

The Corpus of Contemporary American English (COCA) and the British National Corpus (BNC) have frequencies for all words rather than just 80000. And they are professionally compiled and regularly updated corpora, rather than something for which you don't even know the source or date.

If you are looking for lists of words sorted by frequency, COCA has that, too. They have a free 5000-word frequency list, and a 100000-word frequency list that's available for a fee, and some lists in-between.

Solution 2:

I put this together a json file derived from google's N-gram corpus. Raw data for is here:

http://storage.googleapis.com/books/ngrams/books/datasetsv2.html

Data has been ascii-ized, cases were merged and the number is the word count:. These are 58600 of the most frequent words with a cutoff of 1553 mentions in the corpus. (The original purpose was search query normalization)
