The phrase "got one's fingers on" usually means to obtain or get hold of something. Its antonyms, or words with opposite meaning, would be "lost one's grip," "let go," or "released." These terms indicate the opposite action of giving up, surrendering or losing possession. Synonymous phrases such as "give away," "throw away," or "discard" could also be used to show the act of intentionally relinquishing an object or item. Conversely, words such as "keep," "hold onto," or "retain" provide a similar meaning to the original phrase of maintaining possession. Understanding antonyms can widen vocabulary and lead to clearer communication.
