the.com/inverse
the move that quietly undoes you, the only way back is backwards
means The reverse, opposite, or upside-down version of something — the operation or relationship that undoes another.
from From Latin inversus, the past participle of invertere, 'to turn upside down' — in- ('in, into') plus vertere ('to turn'), the same restless root that spins through convert, reverse, and vertigo. Quite literally, a thing turned over.
