The 5,000 most common English words according to the Corpus 5K Word List are below.
NOTE - The COCA-based word list does contain a few proper nouns (mostly relating to places) and a handful of very common abbreviations. However, verb forms, plurals, etc are filtered out (i.e. it is a "Lemma" word list). Words are duplicated in the list if they fall under different parts of speech, so choosing a word that is in the list as a noun and verb will give you two answers. Could only show a few words in the answer due to data field requirements.
