The phrase "gives a pointer" implies providing someone with guidance or a suggestion. Some antonyms for this phrase could be "confuses," "misleads," or "obscures." If someone muddles their guidance or offers a suggestion that is off-base, they may confuse the person they are attempting to help. Similarly, if the suggestion is misleading, it can lead the person on the wrong path. If someone offers an unclear or convoluted directive, it can obscure the solution, further confusing the person seeking help. It is important to be clear, concise, and accurate when giving pointers to ensure they are helpful to the individual in need.
