すべからく

adverb

absolutely ought to; by all means

Classical adverb normally paired with べし or べき, meaning 'must' or 'ought to'. Used in formal or literary contexts; often misused as 'all' or 'everything' in modern Japanese.

• 学がく生せいはすべからく努ど力りょくすべきだ。

  Students absolutely ought to make an effort.

• この問もん題だいはすべからく議ぎ論ろんされるべし。

  This issue must by all means be discussed.

adverb

all; entirely

Non-standard modern usage meaning 'all' or 'everything', derived from confusion with すべて. Considered incorrect by prescriptive grammar, but encountered in casual writing.

• すべからくの人ひとが賛さん成せいした。

  All the people agreed. (non-standard)
