Etymology

Origin of loam

First recorded before 900; from late Middle English lome, earlier lam(e), Old English lām; cognate with Dutch leem, German Lehm “loam, clay”; akin to lime 2

Explanation

Loam is soil — rich soil — that is a mix of sand, clay, and various organic materials. Loam is often used to make bricks. Loam is a type of soil that's got a lot going on: loam contains clay, sand, and decaying organic substances. This combination makes loam particularly useful as a building material. Many bricks are made from loam. It can help you remember loam is used in building if you know that it’s often referred to as "clayey earth." Because of the organic material, loam is also useful as soil for growing crops. This rich soil is helpful in both building and growing.
