noun
flattery; insincere praise; empty compliments
Rare term for hollow or insincere flattery; not commonly used in modern conversation.
彼の言葉はただのからせじに過ぎない。
His words are nothing but empty flattery.
Means flattery or sycophancy, often with a stronger sense of fawning. 空世辞 is rarer and emphasizes emptiness rather than servility.
Compound of 空 (から, 'empty') and 世辞 (せじ, 'flattery'). The exact historical derivation is uncertain, but the spelling reflects the meaning of hollow praise.
