Word Root of LEVER

The Latin word levis, meaning lightweight, gives us the root lev. Words from the Latin levis have something to do with being light in weight. To levitate is to be so light as to rise up into the air. To elevate is to lift something up to a higher level as if it is lightweight. A lever is a bar used to help lift something up by making it feel lighter than it is.
