periscopically

Periscopically is an adverb meaning in a periscopic manner, especially by viewing something indirectly around an obstruction while remaining out of sight. Its use is associated with submarines, military observation, optics, cameras, and other devices designed to provide a concealed or elevated viewpoint. Rather than naming an instrument directly, the word emphasizes the manner of looking: the observer sees beyond a barrier without exposing their position. In ordinary conversation, “through a periscope” or “indirectly” will usually be clearer, but periscopically can be useful in technical writing where precision and formal terminology matter. The word is derived from “periscopic,” an adjective connected with “periscope,” and ultimately with Greek words meaning “to look around.” Although understandable to modern readers, it remains much less common than its instrumental noun.

Etymology of periscopically

The word ultimately comes from Greek periskopein, “to look around,” formed from Greek elements meaning “around” and “to look.” The English word “periscope,” introduced for an optical instrument allowing a viewer to see around obstacles, gave rise to the adjective “periscopic” and then the adverb “periscopically.” The family reflects the original idea of looking around or surveying a concealed area.

How periscopically is actually used
