under erasure: a strategic philosophical device originally developed by Martin Heidegger; involves the crossing out of a word within a text, but allowing it to remain legible and in place; used extensively by Jacques Derrida in his philosophy of deconstruction to signify that a word is "inadequate yet necessary"
In Of Grammatology, Derrida introduced his reading of the Heideggerian strategy of overwriting, which he called "sous-rature."
