The phrase "smash to smithereens" means to completely destroy something, breaking it into tiny pieces. However, there are several antonyms or opposite words that can be used to describe actions that would not result in destruction. These include "repair," "restore," "rebuild," "reconstruct," "mend," "fix," and "heal." All of these words imply a sense of renewal or recovery, rather than destruction. They indicate the process of returning something to its previous state, rather than breaking it down further. While "smash to smithereens" might be an appropriate term for an action movie, in reality, it's rare that something needs to be completely destroyed. These antonyms suggest that there is hope for broken things to be improved and made whole again.
