The Origin of the Phrase “As Dead as a Doornail”

The common expression, “as dead as a doornail,” has a vague yet fascinating origin from the 1300s. It can be traced back to the famous poem of William Langland entitled Piers Plowman. 

The verse goes, “Fey withouten fait is febelore þen nouȝt, And ded as a dore-nayl.” But it is unlikely that the phrase is Langland’s invention.

Langland also translated Guillaume de Palerne, a French poem, into the English language. It reads, “For bu ich haue bote of mi bale I am ded as dorenayl.

Reason to Use It

You might wonder why Langland chose “dead as a doornail” rather than “dead as a coffin nail” when it made more sense. The story goes back to a carpentry concept based on the Morris Dictionary of Word and Phrase Origins.

A technique called clinching creates a dead doornail. It involves hammering the nail on a piece of timber and flattening the edge over the inside, so there’s no way to reuse it. Carpenters used this treatment to make the doornails stronger before screws were invented. 

A doornail is not your average nail that’s in a door. Instead, it’s a large, studded nail on a medieval door that you cannot reuse or remove anymore. Its size and oldness make it dead for proverbs.

Back then, nails were valuable because they were handmade and limited. Those who could not afford nails had to repurpose nails.

Another origin theory of the expression is that people hit a huge doornail with a knocker. The costly metal nails were placed there to make the knocking sound louder. It’s a dark humor that the nails are already dead because many have knocked on its head. 

What Etymologists Have to Say

However, this theory is less credible than the first one. Etymologists favored the first origin because clinching was a widespread practice in carpentry.

So, the phrase “as dead as a doornail” is not only because doornails are inanimate objects. But it’s also because they undergo a specific treatment that causes them to “die.” Its full potential dies like an unreusable doornail.

If one says something is as dead as a doornail, it means it’s a goner. The origins sound convincing, but we may never validate them.  

Poetic Roots of Dead as a Doornail

William Shakespeare did not invent the old expression. It was used in poems before Shakespeare was born, although he may have made the phrase popular through Henry VI, Part 2, in Jack Cade’s speech. The play made it famous all over England in the 16th century.

Charles Dickens also included the questionable phrase in A Christmas Carol. He said:

“Old Marley was as dead as a door-nail. Mind! I don’t mean to say that I know, of my own knowledge, what there is particularly dead about a door-nail. I might have been inclined, myself, to regard a coffin nail as the deadest piece of ironmongery in the trade. But the wisdom of our ancestors is in the simile; and my unhallowed hands shall not disturb it, or the Country’s done for. You will therefore permit me to repeat, emphatically, that Marley was as dead as a door-nail.”

The phrase took off when many civilians who saw the play adopted it. It’s more poetic and famous than other “dead as” phrases.

Some of the “dead as” phrases include “dead as a dodo,” “dead as a doorknob,” and “dead as a dormouse.” Similar expressions include “deaf as a doorknob” and “dumb as a doornail.”

Is Dead as a Doornail a Simile or Metaphor?

“Dead as a doornail” is an idiomatic simile that helps emphasize the adjective “dead.” So, its definition is “very dead,” “quite dead,” or “surely dead.” You can use it in any situation, whether figuratively or literally.

The expression is a simile because it uses “like” to compare things. Similes are figures of speech that use “like” and “as” for comparison. Meanwhile, metaphors directly show comparison without using “like” and “as.” 

“She’s as dead as a doornail” and “she’s dead like a doornail” are similes. “She’s a dead doornail” is a metaphor, but this statement is less used.
