I just bought a new shirt, and it's completely unribbed.

Oh, that's interesting! I usually prefer ribbed textures.

Root Explanation

Unribbed → It is formed from "un-" (meaning not) and "rib" (from Old English "ribbe", meaning a supporting structure or edge). The word "unribbed" means not having ribs or ridges, indicating a smooth surface.

Memory Tip

Think of something that is 'not' ('un-') having the 'supporting edges' ('rib') — that's why unribbed means smooth without ridges.
