When someone is forthright about some kind of information, he/she is being blunt. Blunt does not hint at something but directly states what it is whether or not it may be hard to hear. For example, someone may lie to another about his/her appearance to make he/she feel better, but in reality, the outfit or hairstyle being discussed does not suit him/her at all. One person would try his/her hardest to avoid the hard truth, dropping intimations, as opposed to the blunt person who would directly tell the person that he/she does not look good.

The Great Gatsby: F. Scott Fitzgerald

“Every one suspects himself of at least one of the cardinal virtues, and this is mine: I am one of the few honest people that I have ever known.”
