Meaning and Usage
"決して" (けっして) is an adverb used exclusively with negative verbs to strongly emphasize that something never happens or should never happen. It translates as "never" or "by no means" in English. It is a formal and strong expression often used in warnings, promises, or emphatic statements.
Common Collocations
- 決して〜ない: The most common pattern, meaning "never do ~" or "by no means ~".
- 決して諦めない: "Never give up," a common motivational phrase.
- 決して許さない: "Never forgive," used to express strong refusal or condemnation.
Usage Notes
When using 決して, the verb must be in the negative form. For example, 決して行かない (never go), 決して忘れない (never forget). Using 決して with a positive verb is incorrect.
This word is more formal and emphatic than just using ぜったいに (絶対に) with a negative verb. It is often found in written language, speeches, or serious conversations.
Common Mistake
Learners sometimes try to use 決して with positive verbs, which is ungrammatical. Always pair 決して with a negative verb form to convey the intended meaning.
