Meaning:
To say clearly what you think or feel about something, however unpleasant or awkward it.
To make no bones about something means to say something in a way that leaves no doubt, or to have no objection to it.
The expression comes from fifteenth century England...if someone wanted to show that they were dissatisfied with something, they would find bones in it - a reference to finding bones in soup, which was not a pleasant discovery!
Therefore, finding bones was bad, and no bones was good. If you found no bones, you were able to enjoy the meal with no objections!
Examples:
"He made no bones about his unhappiness with the restaurant's food."
"She makes no bones about her dislike of her husband!"
