upped; upping
Up is a word that means "from lower to higher," so you can use it when you go up in a hot air balloon, when you look up at the clouds, or when you graduate from high school and move up in the world.
As an adjective or adverb, up almost always conveys a movement or position that's higher (or sometimes, northward). You jump up and put your shoes on when you're late for school, turn up the volume on the car stereo when your favorite song comes on, get cheered up by your new kitten, and watch the prices at your favorite bakery go up as it becomes more popular. In the 1500s, the verb up also meant "to catch swans."
