The translation for the German word Gestell, which Heidegger uses to describe his proposal of the essence of technology, which is a self-revealing process, in which truth reveals itself as a standing reserve.

From The Question Concerning Technology

"Enframing means the gathering together of that setting-upon which sets upon man, i.e., challenges him forth, to reveal the real, in the mode of ordering, as standing-reserve. Enframing means that way of revealing which holds sway in the essence of modern technology and which is itself nothing technological."
