Conversation

I learned that the term mudsill refers to the part of a building that rests on the ground.

Really? I always thought it was just a fancy term for something else.

Nope, it’s actually quite important for structural support.

That makes sense! I guess every building needs a strong mudsill to stand firm.

Root Explanation

Mudsill is formed from "mud" (from Old English *mudd*, meaning wet earth or soft soil) and "sill" (from Old English *syll*, meaning a beam or support). The word refers to a foundation or support that is made of mud or is situated in muddy conditions.

Memory Tip

Think of 'mud' as wet earth and 'sill' as a support beam — a mudsill is a support that rests in or on muddy ground.
