A double superlative is a grammar mistake caused by applying two ways of forming a superlative instead of one. Double superlatives are most commonly committed when someone uses "-est" and "most" at the same time (e.g., most tallest).

  • He is the most silliest person I know. wrong cross
  • (should be silliest)
  • She is our most best player. wrong cross
  • (should be best)
  • It's the worstest meal I've ever eaten. wrong cross
  • (should be worst)
The examples above are all double superlatives of adjectives. Occasionally, you see double superlatives with adverbs too.
  • I tried most hardest. wrong cross
  • (should be hardest)
