Etymology: The word is a modern compound, built from two much older pieces. "Photo-" comes from Ancient Greek "phôs" (genitive "phōtos"), meaning "light," which entered scientific vocabulary through combining forms like "phōto-." The second half, "protection," has a longer road: it descends from Latin "prōtegere," "to cover in front," formed from "pro-" (forward) and "tegere" (to cover), and passed into English through Old French and Middle English. Joining the two gives a term that is literally "protection by means of light-related covering," or more plainly, protection against the sun's light. The compound is a straightforward modern coinage, assembled from familiar parts rather than inherited as a single word, which is why its meaning can be read almost directly from its pieces.
