double vertical line

Doesn't this refer to any double vertical line (in which case it's SoP) rather than specifically the math symbol? -- Liliana • 07:04, 22 June 2013 (UTC)

This is the name allocated to it in Unicode. Not all Unicode character names are entry-worthy, however. Equinox ◑ 07:07, 22 June 2013 (UTC)

Strictly speaking the name allocated to it is DOUBLE VERTICAL LINE as they allocate all-caps names. Mglovesfun (talk) 10:30, 22 June 2013 (UTC)

• It seems to me that the generic sense of the phrase "double vertical line" would include a pair of infinite lines, and would also include two vertical lines that were spaced far apart, or even two vertical line segments that were arranged with one on top of the other instead of next to it. If the phrase can demonstrably be used to refer to a specific symbol which is composed of two line segments of equal length that are next to each other in close proximity, then that sense would escape being SoP in my view. See, e.g., 1998, Burkhard Dretzke, Modern British and American English Prononunciation: A Basic Textbook, page 89: "The whole tone unit stands between a double vertical line (double bars) ||". bd2412 T 14:58, 22 June 2013 (UTC)
  • Here is another interesting example:
    • 2007, K. David Harrison, When Languages Die:The Extinction of the World's Languages and the Erosion of Human Knowledge, page 39:

      The ||Gana people (800 speakers—the double vertical line denotes a click sound) of Botswana have no generic word for living things, nor do they recognize a plant versus animal distinction.

  • I think, at least, that if "double vertical line" does not necessarily refer to the math symbol, it is still not SoP if it refers to finite vertical lines that are right next to each other, with matching endpoints. bd2412 T 14:58, 27 June 2013 (UTC)

  There's a "double yellow line", but that's still SOP. --WikiTiki89 04:06, 12 January 2014 (UTC)

• I have adjusted the definition to reflect the non-SOP properties of the lines being closely spaced, and of equal length. bd2412 T 20:59, 7 March 2014 (UTC)
  • I don't think the fact that they are closely spaced and of equal length that makes this idiomatic. Most things that are "double" are both close to each or even adjacent (in either time or space) and of about the same size or importance. --WikiTiki89 21:09, 7 March 2014 (UTC)
    • Something is still missing from the definition, then. The single character, ‖, is something different than || (two adjacent lines rather than a single character). Perhaps the definition should read, "the typographic character ‖" rather than "the symbol ‖". bd2412 T 17:15, 10 March 2014 (UTC)
      • That's exactly the thing, they aren't different except from a typographical perspective. So I guess I would support keeping it as a specific typographical term. --WikiTiki89 17:50, 10 March 2014 (UTC)
        • I have adjusted the definition accordingly. bd2412 T 18:47, 10 March 2014 (UTC)
          • Ok. Keep. --WikiTiki89 18:58, 10 March 2014 (UTC)

Late comment: K. David Harrison seems to be using "double vertical line" as a simple description of the lateral click symbol ǁ. - -sche (discuss) 20:12, 3 April 2014 (UTC)
