Crystal-ball divine refers to the ability to see or predict the future, which is often associated with fortune tellers or psychics. However, its antonyms suggest the complete opposite of this mystical power. Words like clueless, ignorant, unenlightened, and unknowing imply a lack of knowledge or insight into what lies ahead. Rather than gazing into a crystal ball, a person who is clueless has no idea what the future holds. Similarly, someone who is ignorant might be unaware of the implications of certain actions or events. These antonyms highlight the dichotomy between those who claim to know the future and those who accept the uncertainties of life.
