‘Know Him From Adam/Eve’: Definition, Meaning and Examples

By Sophia Merton, updated on May 16, 2023

Did someone say to you, 'know him from Adam/Eve,' and you’re wondering what it means? In this article, we’ll take a look at the meaning, origin, examples, and more.

The short story is that:

  • ‘Know him from Adam’ is an idiom that is almost always used in the negative, as in ‘I wouldn’t know him from Adam’ or ‘I don’t know him from Adam.’
  • You can also say, ‘I don’t know her from Eve’ or ‘I wouldn’t know her from Eve.’ Both of these phrases mean not being able to recognize someone or not knowing someone at all.

What Does 'Know Him From Adam/Eve' Mean?

The phrase ‘know someone from Adam’ means to know or recognize someone. It is almost always used in the negative, as in ‘I don’t know him from Adam’ or ‘I would not know him from Adam.’ This implies that you don’t know someone in the slightest, haven’t ever met them before, or absolutely cannot recognize them.

Though one could say, ‘I don’t know her from Eve,’ it is a much less common idiom. That being said, there is a similar phrase in French that does include Eve:

Je ne connais ni d’Eve ni d’Adam

(Literally: “to know neither from Eve nor Adam”)

The name ‘Adam’ in this idiom refers to the Biblical character Adam, who is considered in Abrahamic religions to be the first man and the individual from which the rest of the human race came.

  • Eve, on the other hand, is the first woman in Abrahamic religions and the mother of the human race.
  • She was the wife of Adam.

In terms of this specific idiom, the reference to Adam and Eve is pointing to the generic concept of all men or all women. Essentially, when you say, ‘I don’t know him from Adam’ or ‘I don’t know her from Eve.’

Where Does 'Know Him From Adam/Eve' Come From?

If you say that you don’t ‘know [someone] from Adam,’ it means that you’ve never met them before or don’t recognize them at all.

  • The reference to Adam refers to the Biblical first man and father of all humans, a story that is said by some sources to date back to the 5th or 6th century BC.

Some sources say that this idiom was first used in the 1800s, but it’s hard to know for sure. You will find some arguing that the idea is that Adam and Eve lived so long ago that a contemporary person wouldn't recognize them. However, the more commonly referenced idea is that the names are used to refer to the generic notion of all men and all women through the use of the names Adam and Eve, respectively.

Examples of ‘Know Him From Adam’ in Text

Using the Google Books Ngram Viewer, we see that 'know him from Adam/Eve’ (and, specifically, ‘know him from Adam’) has been in use since at least 1800.

We find the phrase in “The Old Curiosity Shop” by Charles Dickens, published in 1848:

“‘He called to see my Governor this morning,’ replied Mr. Chucster; ‘beyond that, I don’t know him from Adam.’”

The idiom also appears in a British Parliament text from 1837:

“Are you positive about it? – I have no reason to believe the course differed in this case of Mr. Carr from others, or the man I believe to be Carr; I did not know him from Adam.

It also appears in a collection published in 1841 entitled New British Museum: A Choice Selection From the Works of the Most Celebrated English Authors:

“At last, I come across the boy, on the hill near the house; an’ at last I’m to tell ye why I put the quare story on him ye know about, instead o’ the thru one I thravelled so far to tell him. First, I didn’t know him from Adam, when we met, until he wanted me to take, along wid a brave handful o’ goold an’ silver, a little meddle, like that I remembered, even in the light of a bad moon, was hung round his neck, at the christenin’ of him, by his uncle an’ his godfather, an’ that I often seen afore– an’ maybe the way it came into Collum’s hands, too.”

Examples of ‘Know Her From Eve’ in Text

While the idiom ‘know her from Eve’ is less common than ‘know him from Adam,’ it certainly does appear in some texts as early as the 1800s.

One example of ‘Know her from Eve’ in print appears in a novel called Ups and Downs by Edward E. Hale that was published as a part of a compilation entitled Old and New in 1872:

“But she had been painfully conscious, all the afternoon, that Mrs. Emlen would not know her from Eve or from Adah or from Zillah, except by costume. Nor was it quite clear to Bertha’s mind that Mrs. Emlen would welcome, with the utmost cordiality, a strange girl, who would have to confess in the first moment, that she had just come from an infected vessel, and that she had been all day long hanging over a cholera patient.”

It can also be found in the 1870 text The Ladies’ Repository: Volume 30:

“She insisted that my mother should see her relative, and learn why she came in this unceremonious way, to install herself in her house, who did not know her from Eve nor Adam.”
