Imperative
From Generative Anthropology
An imperative is a command derived from an Ostensive: An action is often warranted when an Ostensive is issue, for example when someone issues the Ostensive “fire!!!”, it’ll imply the Imperative that you should either seek shelter or help put out the fire. An Imperative can also be more explicit like “Pass the salt”, and like the Ostensive, the Imperative is also derived from something currently present at the Scene.
