The word taintest is formed from the combination of two words: taint and the suffix -est.
The word taint originated from the Old French word teindre meaning to dye or to taint. It then evolved through Middle English as taynten or taynten which meant to stain or to corrupt. Over time, it assimilated into the modern English language as taint with the same meanings.
The suffix -est is the superlative suffix used in comparative adjectives in the English language. When added to an adjective, it serves to indicate the highest degree of the quality expressed by the adjective.
Combining taint with the suffix -est forms taintest, which means the most tainted or the most corrupt.
