Estudos que estimam e classificam as palavras mais comuns em inglês examinam textos de todo o mundo.

Talvez a análise mais abrangente seja do Oxford English Corpus (OEC).

No total, os textos no Oxford English Corpus têm mais de 2 bilhões de palavras.

A OEC inclui uma grande variedade de amostras de escrita, como obras literárias, romances, revistas acadêmicas e comerciais, jornais, blogs, salas de bate-papo e e-mails.
