unribbed
Lacking raised lines
Unribbed describes something lacking ribs or rib-like ridges.
The term appears in contexts ranging from textiles to anatomy: unribbed fabric has a smooth weave rather than raised lines, unribbed condoms lack the textured ridges meant to enhance sensation.
The word simply negates whatever ribbed structure might otherwise be expected.
