/ɪnˈtrentʃmənt//ɪnˈtrentʃmənt/The word "entrenchment" has a fascinating history. It originated in the 15th century from the Old French word "tranchier", meaning "to cut a trench". This term was often used in the context of warfare, referring to the act of digging a trench to protect soldiers from enemy fire. Over time, the term evolved to encompass the idea of creating a fortified position or a defensive system, often using trenches and other earthworks. In the 17th and 18th centuries, the term "entrenchment" became prominent in military contexts, used to describe the process of fortifying positions with trenches, redoubts, and other defensive structures. This term was also used in politics and ideology, referring to the process of creating or reinforcing deep-seated ideas or opinions, making them difficult to challenge or change. Today, the word "entrenchment" is used in both military and non-military contexts to refer to the process of creating a strong, fortified position.
