altar

The English word altar comes from Latin altare, recorded in Roman religious writing by the 1st century BCE. In that world an altare was a raised structure for sacrifice, offering, and fire. The form is tied to Latin adolere, "to burn up" or "to sacrifice by burning." The word began with smoke, ash, and ritual action.

Roman religion fixed the term in public life, but Christianity carried it much farther. Late Latin writers in the 4th and 5th centuries used altare for the Eucharistic table as Christian worship took architectural shape. That shift changed the object without erasing the older sense of consecrated offering. A pagan fire-platform became a Christian holy table.

From church Latin the word moved into Old English as alter, probably by the 8th or 9th century. Scribes used it for the fixed sacred table inside a church, not for a generic platform. Middle English spelling later settled into altar under French and Latin influence. The form grew steadier as the ritual setting narrowed.

Modern English kept altar for both literal and figurative use. It is still the table or structure central to sacrifice, communion, or solemn vows. From wedding altars to phrases like "at the altar of ambition," the word keeps its old sense of consecrated offering. The ashes are gone, but the gravity remains.
