Definitions

Etymology: "Holdfast" is a compound of "hold" and "fast," which originally meant "firmly" or "securely" rather than "quickly." Put the two words together and you get a phrase meaning something like "keep firmly," and the noun grew out of that phrase. Over time the phrase was reshaped into a single noun for a grip, clasp or device that holds something fast. The noun's most familiar sense is the mechanical one: a metal fitting or bracket that clamps or fastens an object in place, such as an iron hook or anchor-like catch. The sense of a tight grasp is the figurative extension of that idea, a hold that refuses to let go. The word's core meaning has stayed close to its roots: something that secures, and does not give way.
