tauen

The German word "tauen" is a verb that means "to thaw" or "to melt". It is commonly used in the context of ice or snow warming up and changing from solid to liquid, such as in the phrase "der Schnee taut" (the snow is melting). Similar words in German include "schmelzen" (to melt) and "aufgehen" (to rise or expand, often used for dough).

The key difference is that while "tauen" specifically refers to the transition from frozen to liquid (generally in a natural or gradual sense), "schmelzen" can imply a more active melting, and "aufgehen" typically does not refer to freezing materials but more to processes like baking.
