impurest
Least clean possible
The superlative form of impure—most contaminated, most adulterated, or most morally corrupt.
Though *most impure* is more common in contemporary usage, impurest appears in older texts and deliberately archaic contexts: the impurest thoughts, the impurest water in the kingdom.
