/ˈsaɪlənsə(r)//ˈsaɪlənsər/The word "silencer" has its roots in the late 19th century. It originates from the verb "silence," which means "to make quiet or still." The suffix "-er" is added to denote an agent or instrument that performs the action of silencing. The word first appeared in the 1880s, around the time of the invention of the first effective firearm suppressors. These devices, designed to reduce the noise of gunfire, were initially called "mufflers" or "dampeners." However, "silencer" eventually became the preferred term due to its simplicity and clarity.
