acrylic
acrylic
English (from Latin acer + Greek hylē)
“Acrylic fiber — the synthetic substitute for wool — is named from the same Latin root as 'acrid,' because the chemicals used to make it have a sharp, pungent smell.”
Acrylic comes from acrylonitrile, the chemical monomer from which acrylic fiber is polymerized. The word acrylonitrile was formed from acrylic acid + nitrile. Acrylic acid itself was named from Latin acer (sharp, pungent) + oleum (oil) + Greek hylē (matter, substance) — because propenoic acid, the substance it names, has a sharp smell. The textile takes its name from the chemical, which takes its name from its smell.
Acrylic fiber was developed simultaneously by several companies in the 1940s and 1950s. DuPont introduced Orlon (their acrylic brand) in 1950. Monsanto had Acrilan. Dow had Zefran. The fiber was marketed as a wool substitute — soft, warm, lightweight, moth-resistant, machine-washable. For consumers tired of hand-washing wool and fighting moths, acrylic was liberation.
Acrylic never fully replaced wool despite being cheaper and easier to care for. The fiber has disadvantages: it pills more than wool, does not breathe as well, generates static electricity, and is derived from petroleum. The word acrylic on a sweater label now carries slightly negative connotations among quality-conscious consumers — it means 'not wool.' But for billions of people worldwide, acrylic provides affordable warmth that wool cannot match at the same price.
The word acrylic also names acrylic paint (a polymer suspension), acrylic glass (Plexiglas), and acrylic nails. All use the same base polymer — polyacrylonitrile or its relatives. The sharp-smelling chemical gave its name to fibers, paints, plastics, and cosmetics. The Latin word for pungent became the English word for an entire family of synthetic materials.

Acrylic is in your winter hat, your craft store yarn, your stadium blanket, and your grandmother's sweater collection. The fiber provides warmth at a fraction of wool's cost. It will not shrink, will not felt, and will not be eaten by moths. It will pill, generate static, and melt if it gets too close to a flame.
The word means sharp. The chemical smells sharp. The fiber is soft. The disconnect between the word's origin and the product's feel is total. Nobody wearing an acrylic sweater thinks about pungent chemicals. The word has been laundered as thoroughly as the fabric.
