Etymology: "Photogenesis" is built from two Greek-derived parts: "photo-", from Greek "phōs" (light), and "-genesis", from Greek "genesis" (origin, coming into being). Put together, the literal sense is something like "production by light" or "generation through light." The word works as a compound of the kind formed freely in modern scientific and technical writing, where combining classical elements lets a writer name a new process in a single term. Here the pattern follows familiar models such as "photosynthesis" and "photograph," with the second element borrowed from the same Greek stem that gave English "genesis" and "generate." Because the term is a straightforward modern coinage from classical parts rather than a word with a long oral history, its meaning is defined by its components: the making or generation of something through the action of light.
