What does periscopic mean?
Periscopic is an adjective describing something connected with, seen through, or resembling the viewing arrangement of a periscope. Its most characteristic use is in technical contexts: a periscopic lens or optical system provides a broad field of view, while a periscopic view is an observation made through a periscope. The word can therefore suggest both the ability to look around an obstruction and the use of specialized optical equipment. It is uncommon in everyday conversation, where “wide-angle” or a more specific description is usually clearer. The term is useful in discussions of submarines, cameras, surveying equipment, and optical design, because it identifies a particular way of seeing that differs from ordinary direct observation.
Relating to or viewed through a periscope.
"The officers exchanged periscopic observations of the nearby ships."
Used chiefly in technical and descriptive contexts.
Having a wide field of view, as provided by a periscopic optical system.
"The periscopic arrangement of the lenses gives the instrument a broad viewing angle."
Common in technical descriptions of lenses, cameras, and optical instruments.
A periscopic word looks around corners: its name literally means looking around, from Greek roots meaning “around” and “to look.”

Etymology of periscopic
The word comes from “periscope,” which was formed in the nineteenth century from Greek peri, meaning “around,” and skopein, meaning “to look.” “Periscopic” was developed as an adjective meaning relating to a periscope or viewed through one. It belongs to a family of English scientific words built on the Greek root skopein, including telescope, microscope, and kaleidoscope.
How periscopic is actually used
This is a relatively uncommon, technical term, used mainly in optics, engineering, military contexts, and descriptions of views obtained through a periscope. It is more formal than ordinary alternatives such as “wide-angle.”
Easily confused with periscopic
