There's No Way (〜わけがない)
〜わけがない
Strongly denies a possibility, meaning 'there's no way that' or 'it's impossible that.' Expresses firm disbelief.
Pattern
Plain form + わけがない
Explanation
〜わけがない is used to strongly deny a possibility or assert that something is absolutely impossible. It expresses the speaker's firm conviction that something cannot be true.
Formation: [Plain form] + わけがない. For verbs: 知っているわけがない (there's no way they know); for い-adjectives: 安いわけがない (there's no way it's cheap); for な-adjectives: 簡単なわけがない (there's no way it's easy); for nouns: 学生なわけがない (there's no way they're a student).
This is stronger than 〜はずがない (it shouldn't be) and expresses logical impossibility from the speaker's viewpoint. It often carries an emotional tone of disbelief or indignation.
