  • THIS-UNDECORATED denotes the formative before attaching the affix in question.
  • CONTEXT denotes the current semantic context, environment or universe of discourse, which is described by the current formative and possibly other formatives.
  • ANOTHER denotes another participant of CONTEXT distinct from THIS.
  • ATTACHED denotes the connected semantic context, presupposition, events or fact mentioned earlier or to be mentioned or assumed from CONTEXT.
  • SPEAKER is the one who says the current text.

Roughly, THIS corresponds to the current word, CONTEXT to the current clause/sentence/case frame and ANOTHER to another noun in CONTEXT. ATTACHED are usually previous sentences or a greater context that led to the current more narrow CONTEXT.
