In tip-top shape

Origin

The phrase "tip-top" itself emerged in the early 19th century as a whimsical, reduplicative intensifier, painting a vivid picture of something reaching the absolute peak of excellence—the very "tip" of the "top." Initially, it might have described anything from a fashionable hat to a superior dish. But when paired with "shape"—a word referring to the general condition or physical form of a person or object—the phrase found its true calling. It conjured the image of an individual or item performing at its absolute best, perfectly prepared, honed, and in prime condition, as if balanced precariously yet confidently at the very summit of its potential.
