Etymology 1

[edit]

From Middle English core, kore, coor (“apple-core, pith”), of obscure and uncertain origin. Possibly of native English origin, from Old English *cor, related to Old English *coruc, *corc (diminutive) (> Middle English cork, crok (“core of a apple or other fruit, heart of an onion”)) and Old English corn (“seed", also "grain”); or alternatively perhaps from Old French cuer (“heart”), from Latin cor (“heart”); or from Old French cors (“body”), from Latin corpus (“body”). Compare also Middle English colk, coke, coll (“the heart or centre of an apple or onion, core”), Dutch kern (“core”), German Kern (“core”). See also heart, corpse.

    • 2013 June 22, “Engineers of a different kind”, in The Economist, volume 407, number 8841, page 70:
      Private-equity nabobs bristle at being dubbed mere financiers. Piling debt onto companies’ balance-sheets is only a small part of what leveraged buy-outs are about, they insist. Improving the workings of the businesses they take over is just as core to their calling, if not more so. Much of their pleading is public-relations bluster.

    • 2023, Mari Kristin Sisjord, Women in Snowboarding:

Verb

[edit]

core (third-person singular simple present cores, present participle coring, simple past and past participle cored)

  1. To remove the core of an apple or other fruit.
  2. To cut or drill through the core of (something).
    • 2020 April 1, Drachinifel, 6:52 from the start, in HMS Thunderchild - A bad day to be a Tripod‎[1], archived from the original on 24 September 2022:
      But the other thing to take into account is, when you look at the Katahdin and the Polyphemus, they both have their boiler plants pretty much amidships or slightly forward of amidships, which means that, in the event of a heat-lance strike on the boiler room, not only is that gonna core through the ship right at the center of mass, which is obviously bad for its continued structural stability, but the boilers going up is gonna incinerate pretty much anybody on the bridge, which is gonna leave it completely out of control, and is probably gonna break the ship clean in half right there and then, none of which really speaks to the ship's being able to continue onwards with enough momentum to take down a Martian tripod.
  3. To extract a sample with a drill.

      It's more than okay to let a microtrend be just that. Naming it as a "core" turns the clothing into a social media movement, and more often than not, the title is an overcomplication for rather basic color choices or fabric selections.

      The aesthetic makes a convincing case for finding joy in fashion and experimenting with personal style rather than chasing every new 'core' that comes along. It encourages real excitement about getting creative with the clothes you already have in your wardrobe and therein lies the thrill of it.
