'Not Known From Adam' Idiom Meaning and Examples

The phrase “not known from Adam” is a slang expression used to describe someone who is not well-known or not at all familiar to the speaker. It is similar to saying the person is “unknown” or “an unfamiliar face”.

The phrase likely originates from the bible, in which Adam was the first man and the father of the human race. The phrase implies that the person is so unknown that even Adam, the father of all mankind, does not recognize them.

This idiom can be used to describe someone who is unfamiliar or unknown to the speaker. For example, if you are meeting someone for the first time, you could say, “I don’t know him from Adam.”

This phrase can also be used to describe someone who is not well-known in their field of work or who is not widely recognized. For example, you could say, “She’s not known from Adam in the music industry.”

Additionally, the phrase can be used to show that someone is not well known or is not very important. For example, you could say, “He’s not known from Adam in the business world.”
