About this person
Some older scholarship has proposed a Brittonic derivation, *calg‑ac‑os, meaning 'possessing a blade' or 'swordsman', but this interpretation is highly speculative and not attested in contemporary sources. Several scholars have connected the name Calgacus with the Gaelic root calg-, meaning "a prickle; the point of a weapon; anything pointed". Related forms recorded in Dwelly's Illustrated Gaelic-English Dictionary include calgach, calg and calgag ("pointer-finger"), all belonging to the same semantic field of pointed or projecting objects. MacBain's Etymological Dictionary of the Gaelic Language also records calg / colg as meaning "awn, bristle; anything pointed; a sword". Whether the word is a name or a title is unknown.
