noun
-
An area of low-lying wetland in which the level of water is generally shallow and often fluctuating. The water may be either standing or slow-moving. The water in a marsh is also more or less neutral or alkaline, in contrast to the water in a bog, which is acidic. The environment of a marsh is in general well-oxygenated and nutrient-rich and allows a great variety of organisms to flourish. In contrast to a swamp, in which there is an abundance of woody plants, the plants in a marsh are mostly herbaceous. Reeds and rushes dominate the vegetation of marshes.

Etymology
Origin of marsh
before 900; Middle English mershe, Old English mer ( i ) sc (cognate with German Marsch ). See mere 2, -ish 1; cf. marais, marish, morass
Explanation
A marsh is an area in transition from land to water. It is a very bad idea to go walking in a marsh in your best shoes; try some fishing boots, or perhaps a boat. The word marsh comes from the old Dutch word mere, for sea, and it means land that is sea-ish… not sea, but sea-ish, like most of Holland. Marshes can be found often where a river empties into the sea, or along the side of a low, flooded river. Another word for marsh is swamp. If you’re in trouble or just want to be alone, a marsh is a great place to hide: no one will follow you. Just don’t forget your galoshes.
