The term 'Like a Fen' is used to describe an area of land that is MARSHY and BOGGY. MARSHY refers to land that is wet and often flooded, while BOGGY refers to land that is soft and spongy due to the presence of water. These areas are often found in wetlands, which are areas of land that are saturated with water and have a high water table. Wetlands are important ecosystems that provide habitat for many species of plants and animals.
