## Origin

From Middle English "columne," borrowed through Old French "columne" from Latin "columna" (a column, pillar, or post), originally a variant of "columen," contracted to "culmen" (a pillar, top, or summit). It is related to Latin "collis" (a hill) and "celsus" (high), and probably to Ancient Greek "kolophōn" (top, summit).
