Cách sử dụng
The word 'overground' is used to describe something that is above ground level, and not underground or beneath the surface. For example, an overground train or railway system travels on tracks above the ground, while an underground train or subway system travels below the ground. In everyday conversations, 'overground' is often used to indicate something that is visible or open to the sky, like an overground swimming pool, an overground garden, or an overground car park. So, if you hear someone using the word 'overground', they are most likely referring to something that is above ground level and in plain sight.
