Etymology

The word "bromide" originates from the element bromine (discovered in 1826, named after Greek bromos "stench" due to its sharp odor) combined with the suffix -ide, used in chemistry to denote binary compounds. By the late 19th century, "bromide" metaphorically extended to describe dull, predictable statements—inspired by the sedative effect of potassium bromide, which was widely prescribed at the time. This dual meaning reflects both scientific and cultural history.
