Double SuperlativesA 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 (e.g., most tallest).
Easy Examples of Double Superlatives
- He is the most wisest. [wrong] (should be wisest)
- She is the most quickest. [wrong] (should be quickest)
