Variant of Ambrose, from Greek ambrosios meaning 'immortal' or 'divine'.
Ambrous is a variant of Ambrose, ultimately from the Greek ambrosios, meaning "immortal" or "divine." That root gives the name an elevated, almost mythic quality, and it has long belonged to the family of names associated with sacredness, endurance, and spiritual favor.
It feels like a form that has drifted a little from the standard spelling while keeping the old meaning intact. Because Ambrose itself has a long history in Christian and classical tradition, Ambrous inherits a sense of age and seriousness even as the spelling looks fresh and uncommon. The name is rare, which makes it feel distinctive without losing the familiar cadence of the original. It has the sort of sound that can seem both scholarly and slightly legendary, a small variation that still carries a large historical shadow.
