The compound "wide-angle" is a modern English formation that transparently combines two native and borrowed elements to describe a specific geometric or optical property. The first element, "wide," is a fundamental Germanic adjective from Old English wīd, ultimately from the Proto-Indo-European root wi-, conveying the sense of apart or asunder, which evolved to mean broad or extensive. The second element, "angle," entered English via Old French from Latin angulus (corner), a term of uncertain but possibly Proto-Indo-European origin related to bending. When combined, the literal meaning "broad corner" logically evolved in technical contexts, particularly optics and photography, to denote a lens or view that encompasses a broad field of vision, effectively seeing more within the "corners" or periphery of a scene.

Structure: wide (broad) + angle (corner, space between intersecting lines) - wide: From Old English wīd (spacious, vast). An adjective describing great extent from side to side. - angle: From Latin angulus (corner). A noun denoting the space between two intersecting lines or surfaces.
