History

Etymology

From Middle English Slo, perhaps related to the noun slough (“marsh”) (referring to the land) or to sloe (referring to bushes).

From Middle English slogh, slugh, slouh, from Proto-Germanic *sluk-, perhaps related to *sleupaną (“to slip, sneak”) (compare Gothic 𐍃𐌻𐌹𐌿𐍀𐌰𐌽 (sliupan)). Akin to Middle Low German slô (“sheath, skin on a hoof”). Perhaps also related with Old Saxon slūk (“snakeskin”), Middle High German slūch, whence German Schlauch (“waterskin, hose”).

From Middle English slough (“muddy place; swamp; mire”), Old English slōh, probably from Proto-Germanic *slōhaz.
