As the Catechism does not use the specific word gossip, let’s look at its secular definition and apply that to the Catechism’s discussion. Here are the first three definitions from [Dictionary.com (http://dictionary.reference.com/search?q=gossip):
1.) Rumor or talk of a personal, sensational, or intimate nature; 2.) A person who habitually spreads intimate or private rumors or facts; 3.) Trivial, chatty talk or writing.
Definition three is idle chatter. So long as it does not show disrespect for the reputation of another and so long as it does not supercede other necessary responsibilities, there is nothing wrong with it. Definition one fits the Catechism’s discussion of both rash judgment and detraction. If the person knew that the rumors he were spreading were false but deliberately spread them anyway, it would be calumny. Definition two is simply a colloquial term for a person who engages in the acts discussed in definition one.
In short, gossip can be harmless if it does not disrespect another’s reputation and if it does not keep someone from attending to his responsibilities. Gossip becomes harmful and possibly sinful when it includes rash judgment, detraction, or calumny.
