Morphology

impurity = impure (transparent) = im + pure + ity

Formed by adding the noun-forming suffix '-ity' to the adjective 'impure', a standard and predictable derivation.

Etymology

Impurity comes from the Latin parts in- 'not' and purus 'pure', so it literally means 'not pure'. Think of an impurity as a small unwanted thing — like a speck of dirt or a wrong chemical — that makes water, metal, or food not pure.
