As of January 2021, English-Corpora.org has now made available for download, at no cost, its most up-to-date (as of late 2019)
Top 5000 lemmas frequency list on their WordFrequency.info site. The free downloadable list in Excel format can be found
here.
The partial list is extracted from the Corpus of Contemporary American English's frequency data, described as "probably the most accurate
word frequency data for English...based on the one
billion word Corpus of Contemporary American English (COCA)
-- the only corpus of English that is large, up-to-date, and
balanced between many genres".
What's impressive is that, unlike other lists, this particular list covers 8 genres: blogs, other web, TV/Movies, (more formal) spoken,
fiction, magazine, newspaper, and academic.
Just thought the above was worth sharing...
