Marais is a French term that is commonly translated into English as either marsh or swamp. Both terms refer to a wetland area that is typically saturated with water. However, there are a few other synonyms that can be used to describe such landforms. For example, the term bog is often used to describe a peatland area that is dominated by mosses. Meanwhile, the term fen is used to describe a type of bog that has a higher water level and supports the growth of plants such as sedges and reeds. Finally, the term wetland is often used as a general term to describe any area that is wet and supports a distinctive community of plants and animals.
