The antonyms for the word "in-vented" are "uninvented" or "discovered." While inventing something involves creating or designing something new, uninventing means to undo or dismantle it. On the other hand, discovering involves finding something that already exists but wasn't previously known. While inventing is a creative process that brings new ideas, products, or solutions to the world, uninventing or discovering could mean taking a step back and reevaluating existing ideas or reimagining them. Both uninventing and discovering could be as valuable and impactful as inventing if done skillfully and with a purpose.
