blue-chip

The term 'blue-chip' originated in the world of gambling, specifically poker, in the early 20th century. In poker, chips of different colors represent different monetary values, with blue chips traditionally being the most valuable. This literal sense of high-value tokens was then metaphorically transferred to the stock market in the 1920s. It was used to describe the stocks of large, well-established, and financially sound companies, implying they were the safest, most valuable "bets" for investors. Thus, the logic of the word evolved from a concrete gambling token to an abstract financial and qualitative designation.

Structure: blue (color) + chip (token) - blue: From Old English 'blāw', of Germanic origin. In this compound, it refers to the color of the highest-value chips used in poker. - chip: From Old English 'cipp' (a small piece of wood).
