An archaic legal or religious term for appearance together, or the state of standing together as sponsors or witnesses.
From compear + -ance suffix (from Latin -antia). This is a legal/ceremonial term that emerged in medieval religious contexts.
Medieval legal documents are filled with 'compearance' to describe when witnesses appeared together—as written language became more standardized, such specialized ceremonial words got replaced by simpler alternatives like 'appearance' or 'presence.'
