Borrowed from Latin collum (the neck). Doublet of col.



collum (plural colla)

  1. (anatomy) A neck, cervix, or neckline part or process.
    • 1882, Frank Coles Phillips, Proceedings of the Bristol Naturalists' Society, volume 3, page 25:
      No sooner does a little particle of food touch the edge of the delicate collar which surrounds the collum, than it adheres to it and is carried down by currents, that circulate up one side of the collar and down the other, to the end of the collum, in which, along with an accompanying drop of water, it becomes at once engulped[sic].
  2. (botany) A collar[1]

Alternative forms[edit]


Uncertain, but perhaps from Proto-Italic *kʷolsom, from Proto-Indo-European *kʷolso- (neck, literally that on which the head turns), from *kʷel- (to turn). Typologically compare Old Armenian պարանոց (paranocʿ, neck).

See also Old English heals (neck, prow of a ship) (whence English halse (neck, throat)), Middle Dutch and Old Norse hals (neck).
