The term "value-free" is a modern English compound, primarily emerging in 20th-century academic discourse, especially in the social sciences. It combines the noun "value," which traces back to the Latin valēre (to be strong, have worth), with the adjective "free," from Old English, used here in its sense of "being without." The literal construction "free from values" reflects a methodological ideal: to conduct analysis or make statements that are not colored by the investigator's own moral or cultural principles. This concept is central to debates about objectivity, particularly associated with Max Weber's advocacy for Wertfreiheit (the German equivalent) in sociological research, aiming to separate factual description from ethical evaluation.

Structure: value (worth) + free (without) - value: From Old French value (worth), from the feminine past participle of valoir (to be worth), from Latin valēre (to be strong, be worth). In this compound, it functions as a noun meaning "worth" or "principles." - free: From Old English frēo (free, exempt from), from Proto-Germanic frijaz. In this compound, it functions as an adjective-forming element meaning "without" or "lacking."
