"Gives the low-down" refers to providing honest and accurate information about a particular situation or topic. Its antonyms could be "misleads," "deceives," or "withholds information."
When someone misleads or deceives, they distort the truth, leading others to believe something untrue or incomplete. Withholding information could mean deliberately avoiding sharing crucial details, which could result in incomplete decision-making.
To effectively communicate with others, it's critical to be transparent and forthcoming with information, especially if it's relevant to their decision-making. By providing an honest low-down, one can build trust, credibility, and foster a more harmonious relationship with others, leading to better outcomes for all involved.
