Word Root of GRAVITY
The Latin word gravis, meaning “heavy” or “serious,” gives us the root grav. Words from the Latin gravis have something to do with heaviness or seriousness. Something grave, or important, such as a situation, requires serious thought and consideration. To aggravate is to make a situation more serious. Gravity is a force that pulls everything towards the ground making it feel heavy.
