texture's way of saying don't slip, gripped before grip was cool.
means Having a series of raised lines, narrow crests, or wales running across a surface.
from From "ridge," Old English "hrycg," meaning the back or spine — the same word once used for the literal backbone of a person or animal, and for the long crest of a hill where the land seems to arch its spine against the sky. From there it spread to anything with that raised, running line: the peak of a roof, the wales of corduroy, the grip-grooves of a tire. The "-ed" simply turns it into a description: a thing that wears those spines. It's a cousin of Dutch "rug" and German "Rücken," both still meaning "back" — so a ridged surface is, etymologically, a surface with backbone.
