It’s summer time in the Northern Hemisphere and here in Germany as the weather heats up, it also means that the potential for heavy rain increases. A common phrase that is used in English to describe heavy rain, is to say, “it is raining cats and dogs”. Now obviously this doesn’t mean that cats and dogs are falling out of the sky, but rather it is a way to illustrate that not only is it raining but that it is raining very heavily.
One theory of the origin of this phrase in English comes from 17th century England. It was believed that when it rained heavily that the gutters that were used to collect rain water and funnel it to the sewer system would overflow. Given that the sanitary conditions of the time were not very high, this meant that anything that was in the gutter would flow through the streets. Sometimes this would include dead animals, such as, cats or dogs. So the expression became that when the rain was really heavy, then it was raining cats and dogs.
