    • A style of marking or pattern: In a broader sense, "dot-and-dash" can describe any pattern or sequence composed of alternating dots and dashes.

  2. Adjective:

    • Relating to or using a dot-and-dash code: Used to describe something that employs or is characteristic of such a system, especially Morse code.

Advanced Usage

  • "Dot-and-dash code": a specific reference to Morse code or any similar encoding method.
