"Caused" and "adopt" are two words that have very different meanings, and as such, one might wonder about antonyms for these two words together. As "caused" refers to an action that leads to a specific outcome, its antonym would be "prevented" which means to hinder or stop the occurrence of an event. "Adopt," on the other hand, means to take something on as one's own, and its antonym would be "abandon" which refers to leaving something behind or giving up on it. These antonyms have very different connotations and can be used in various situations to convey different meanings.
