The word 'trench' refers to a long and narrow ditch or excavation made in the ground. It is often used for military purposes, such as a defensive fortification during a war. Trenches are also used in construction to attain a flat base or to redirect water. In addition, they can be found in gardens to create a defined garden bed. Trenches can be of varying depths, and are typically dug using heavy machinery or shovels.
