These days it became very cold in the morning and evening. We will be afraid of not only corona virus but also influenza virus. By the way, do you know the origin of the influenza? The word influenza came from ''influence of the star''! Ancient people who didn't know the idea of virus thought that the influenza occurred due to the influence of the operation of celestial bodies. I knew this story in today's class and I felt the origins of words are very interesting. I would like to investigate the origin of other words.
