Logorrhea

Does logorrhea (lah-guh-ree-uh)sound like another word you know? It kind of sounds like diarrhea, doesn't it. There is a reason for that. Logorrhea is sometimes rudely called diarrhea of the mouth. 

People who talk incessantly, or non-stop, with nothing much to really say are guilty of logorrhea. They chatter on and on.

It is important to note, however, that sometimes people can't help it. They are lonely, or super intelligent, or it can even be a mental disorder. It is kind to listen to someone with logorrhea as long as it is convenient to do so. They aren't being rude. They just need someone to listen.

These two are engaged in a great battle of logorrhea!!!
