Etymology Origin:
The word binoculars emerged in the 18th century, combining Latin roots to describe a dual-lens device (bin- + ocul-). The suffix -ars (a variant of -ary) solidifies its noun form. The term logically mirrors the instrument’s purpose: "two-eyed viewing." Its construction parallels other scientific terms like bicycle (bi- + cycle) but focuses on vision.
