平坦

平坦 refers to a surface that is level and even, without hills or bumps. It is commonly used to describe land, roads, or other physical surfaces that are smooth and unbroken.

The character 平 (píng) means 'level' or 'even,' while 坦 (tǎn) means 'open' or 'flat.' Together, they form a compound that emphasizes the idea of an even, unobstructed surface.

平坦 is often used in geographical contexts, such as describing landscapes or urban planning. It can also be used metaphorically, though less commonly. In daily conversation, it is most frequently encountered when discussing terrain, construction, or travel conditions.
