Yahveh is a spelling variant of Yahweh, the Hebrew sacred name of God.
Yahveh is a spelling variant of Yahweh, the Hebrew sacred name of God. The difference is small visually, but the significance remains the same: this is a form tied to biblical reverence and sacred speech.
It belongs to a lineage of transliterations that attempt to render the divine name into Latin script. In use, Yahveh feels serious, scriptural, and highly specific. It is less a fashionable given name than a sacred form that has occasionally been used as one.
The spelling gives it a slightly more formal and archaic look than some alternatives. Yahveh carries the weight of theological history in a very direct way.
