What Adam actually means
Adam is the Hebrew word for man. Behind the Name says it may go back to a Hebrew root meaning to be red, after the ruddy colour of human skin, or to the Akkadian adamu, to make.
The familiar earth connection sits to one side of that. It appears in the Genesis account as a word play on adama, earth, and is not among the derivations Behind the Name proposes. The name has been common in English since the Middle Ages, and it gained ground after the Protestant Reformation.
