ETYM Cf. as. swam a fungus, od. swam a sponge, Dutch zwam a fungus, German schwamm a sponge, Icel. svöppr, Dan. and Swed. swamp, Goth. swamms, Greek somphos porous, spongy.
1. A situation fraught with difficulties and imponderables.
2. Low land that is seasonally flooded; has more woody plants than a marsh and better drainage than a bog.
Region of low-lying land that is permanently saturated with water and usually overgrown with vegetation; for example, the everglades of Florida, US. A swamp often occurs where a lake has filled up with sediment and plant material. The flat surface so formed means that runoff is slow, and the water table is always close to the surface. The high humus content of swamp soil means that good agricultural soil can be obtained by draining.
To drench or submerge or be drenched or submerged; SYN. drench.
