The word "re-eked" itself doesn't have antonyms, as it is not a widely-used word in the English language. However, if we break down the two parts of the word, "re-" (meaning again) and "eked" (meaning to scrape by or barely manage), we can find antonyms for each part. Antonyms for "re-" could include "never again," "for the first time," or "once." Antonyms for "eked" might include "prospered," "thrived," "proliferated," or "flourished." It's important to use the correct antonym depending on the context and meaning of the original word.
