Act or speak frankly about something, without hesitation or evasion. For example, Tom made no bones about wanting to be promoted, or Make no bones about it--she's very talented. Versions of this expression date back to the mid-1400s and the precise allusion is no longer known. Some believe it meant a boneless stew or soup that one could eat without hesitation; others relate it to dice, originally made from bones, that were thrown without hesitation or fuss.
