The name Adam: origin and meaning

Adam is a name of Hebrew origin, meaning "Man, earth". It has travelled across Europe for centuries — its earliest bearer in the Christian tradition is Adam, first man in the Book of Genesis, and in modern times it has become widely recognised through cultural figures such as Adam Smith (economist), Adam Driver (actor).

In Portugal, the name connects to Adam, first man in the Book of Genesis, which keeps it firmly embedded in the Catholic naming tradition and the local saints' calendar.
