loam
Loam (noun) means a rich type of soil made of sand, silt and clay together with rotted plant matter.
Etymology
This word came into English through Middle English lom, lome, from Old English lām (“clay, mud, mire, earth”), from Proto-West Germanic *laim, from Proto-Germanic *laimaz, *laimô (“clay”), tracing ultimately to Proto-Indo-European *h₂leyH- (“to smear”). It is a cognate of Saterland Frisian Leem (“loam”), West Frisian liem (“loam”), Dutch leem (“loam”) and German Lehm (“loam”), and is also related to lime.
