non-lethal

The word is a modern English compound formed by directly combining the Latin-derived negative prefix "non-" with the adjective "lethal." "Lethal" itself descends from the Latin letalis, meaning "deadly," which is connected to letum (death), a word of Proto-Indo-European origin. The logic of the construction is transparent and literal: "not" plus "deadly." It emerged in the 20th century, primarily in military, law enforcement, and scientific contexts, to categorize weapons, force, or agents specifically designed to incapacitate or deter without causing fatal injury, thus creating a crucial semantic distinction from traditional "lethal" means.

Structure: non (not) + lethal (causing death) - non: Latin origin, a prefix meaning "not" or "without," serving a negating function. - lethal: From Latin letalis (deadly), related to letum (death). It functions as the core adjective meaning "causing death."
