List of idioms attributed to Shakespeare

The influence of William Shakespeare on the English language is pervasive. Shakespeare introduced or invented countless words in his plays, with estimates of the number in the several thousands. Warren King clarifies by saying that, "In all of his work – the plays, the sonnets and the narrative poems – Shakespeare uses 17,677 words: Of those, 1,700 were first used by Shakespeare." He is also well known for borrowing words from foreign languages as well as classical literature. He created these words by "changing nouns into verbs, changing verbs into adjectives, connecting words never before used together, adding prefixes and suffixes, and devising words wholly original." Many of Shakespeare's original phrases are still used in conversation and language today.

While it is probable that Shakespeare created many new words, an article in National Geographic points out the findings of historian Jonathan Hope who wrote in "Shakespeare's 'Native English'" that "the Victorian scholars who read texts for the first edition of the OED paid special attention to Shakespeare: his texts were read more thoroughly and cited more often, so he is often credited with the first use of words, or senses of words, which can, in fact, be found in other writers."
