What does pureness mean?
Pureness is the noun form of pure and denotes the quality of being completely free from contamination, adulteration, or corruption. In its most literal sense, it describes water, food, chemicals, or other substances whose contents are uncontaminated. Extended uses refer to clarity, authenticity, simplicity, and moral innocence: a person may speak of the pureness of motives, while a critic may praise the pureness of an artistic style that has not been diluted by imitation. The word is less frequent than the more familiar noun purity, but it can carry a slightly more emphatic or formal tone. It is especially useful when describing something in an exceptionally pure or unaltered state, such as the pureness of a natural spring or a chemical sample.

Where does pureness come from?
Pureness ultimately comes through Old English pūre, from Latin purus, meaning “clean” or “uncontaminated.” The same Latin root also produced forms such as purify, purification, purist, and impurity. English began using purity in the medieval period, while the suffix -ness was added to the adjective in the early 16th century to form pureness.
How pureness is actually used
Pureness is less common than purity and can sound formal, emphatic, or occasionally old-fashioned. It is especially natural when discussing the unaltered quality of water, food, air, or a sample.
