Reified means to turn abstract concepts into concrete objects, so antonyms could include: abstract, intangible, theoretical, immaterial, imaginary, insubstantial, spiritual, metaphysical, or idealistic. These words imply a lack of physicality or material form, as opposed to reified which suggests an actual existence. Other antonyms could be deconstructed, analyzed, dissected, dismantled, or fragmented, which would suggest breaking down a concrete object into abstract concepts. These antonyms reveal the opposite process of reification, or the deconstruction of something that has been made concrete. Ultimately, these antonyms can help us understand the meaning and importance of reification in creating tangible representations of abstract ideas.
