The term 'higher than' can be expressed in three different ways: ABOVE (5 letters), OVER (4 letters), and Ontopof (7 letters). ABOVE is used to describe something that is located higher than something else, such as a mountain being ABOVE the clouds. OVER is used to describe something that is higher than something else, but not necessarily directly ABOVE it, such as a plane flying OVER a city. Ontopof is used to describe something that is directly on top of something else, such as a book being placed ontopof a table.
