決して~ない (never)
grammar44 sentences
The strong-negation adverb 決して combined with a negative predicate, meaning 'never / absolutely not / by no means / in no way.' A fixed adverbial frame, requiring negation. Adds emphatic finality far more forceful than mere ない. Common in declarations of principle, refusal, and conviction: 決して諦めない ('I will never give up'), 決して許さない ('I will never forgive'). The kanji form 決して is standard; the kana けっして is an occasional variant.
