Meaning and origin of Cain
Cain is a Hebrew name that is usually said to mean “acquired”.
Cain comes from the Hebrew Qayin. In the Book of Genesis, Eve explains the name with a word meaning I have acquired, though scholars also connect it to a word for smith or spear, so its original sense is not certain. Cain is the elder son of Adam and Eve, who killed his brother Abel. Because of this story, the name has long had a dark reputation, though some parents today choose it for its strong, simple sound. It is also spelled Kane. Cain pairs well with classic middle names.
Other spellings with the same sound: Kane, Kain, Kaine, Kayne, Caine, Cayne, Cane.
