What does unpolluted mean?
Unpolluted is an adjective meaning free from pollution, contamination, or other forms of damage. Its most common use describes water, air, soil, food, or natural landscapes that have not been spoiled by harmful substances or human interference. It can also be used figuratively for people, institutions, reputations, or processes that remain free from corruption, scandal, and dishonest influence. The word often carries a positive connotation because it suggests both physical cleanliness and moral integrity. It is especially common in environmental and scientific writing, where precision matters, but it can appear in journalism and general prose when the emphasis is on something remaining untouched or uncompromised. In contexts such as “unpolluted by corruption,” the figurative sense becomes particularly clear. Although unpolluted is related to pollution, it does not merely mean that pollution has been removed; it describes something that has remained free from it.

Where does unpolluted come from?
Unpolluted is an English word formed by combining the prefix un-, which reverses or negates a meaning, with pollute. Pollute entered English through Old French polluer, ultimately from Latin pollutus, the past participle of polluere, meaning “to defile” or “make foul.” The prefix and base were combined in English to form an adjective describing something not spoiled or contaminated.
