In this context, as in the more ordinary sense, it is a mapping of speech sounds to symbols, usually written, but some others have made systems that make use other things such as color (lights, or pigments) or even 3d-shapes. So, for example, the Latin alphabet is a writing system, but so are the Arabic abjad, the Devanagari abugida, the Mongolian script, the Korean script, Gregg shorthand, as well as Tengwar and Klingon. The last two are considered conscripts (a synonym for neography, in hindsight, I should have used that instead) since they aren’t used to write “natural (human) languages”.
