Column
late Middle English: partly from Old French columpne, reinforced by its source, Latin columna ‘pillar’.
wiktionary
From Middle English columne, columpne, columpe, borrowed from Old French columne, from Latin columna(“a column, pillar, post”), originally a collateral form of columen, contraction culmen(“a pillar, top, crown, summit”). Akin to Latin collis(“a hill”), celsus(“high”), probably to Ancient Greek κολοφών(kolophṓn, “top, summit”).
etymonline
column (n.)
mid-15c., "a pillar, long, cylindrical architectural support," also "vertical division of a page," from Old French colombe (12c., Modern French colonne "column, pillar"), from Latin columna "pillar," collateral form of columen "top, summit," from PIE root *kel- (2) "to be prominent; hill."
In the military sense "formation of troops narrow in front and extending back" from 1670s, opposed to a line, which is extended in front and thin in depth. Sense of "matter written for a newspaper" (the contents of a column of type) dates from 1785.
