Hi there and welcome to this week’s Words and Their Stories. On today’s show we will talk about an idiom of warning. And it is not very easy to say. Loose lips sink ships. This idiom began during World War II as a slogan used by the United States Office of War Information. It was part of a propaganda campaign. So, the slogan loose lips sink ships was printed on posters and hung in many public places, such as schools and churches. This wartime expression warned people in the military as well as ordinary citizens to watch what they say. Unguarded talk may give useful information to the enemy.
