whale-fin

A whale-fin is used to stiffen the bodice of a historical dress.

Definition

1. Noun:
   • A horny, flexible substance: "whale-fin" refers to the baleen plates found in the mouths of certain whales (such as the right whale), used to filter food from water. It is a keratinous material, historically valuable for making items like corset stays, brushes, and umbrella ribs.
   • Alternative term for whalebone: In commercial contexts, "whale-fin" is synonymous with "whalebone," though technically whalebone is a misnomer for baleen.

Usage Examples

• Noun:
  • The corset was stiffened with whale-fin to give the wearer a narrow waist. (The garment used this horny substance for structure.)
  • Whale-fin was once a common material for making umbrella ribs before plastic became available. (The material was used for its flexibility and strength.)

Advanced Usage

• "Whale-fin" in historical trade: The term often appears in discussions of 18th- and 19th-century whaling industries, where the material was a major commodity.
  • The whaling ship returned with a cargo of oil and whale-fin. (The ship carried both valuable whale products.)

Variants and Related Words
