Look daggers means to glare with hostility, anger, jealousy, or hatred. In poetry, the idiom turns a look into a weapon, making silence aggressive and visually sharp. It is useful in dramatic scenes where words are withheld but feeling is unmistakable. A jealous lover, rival, betrayed friend, or resentful crowd may look daggers. The phrase helps students see how idioms can convert facial expression into metaphorical action, suggesting that violence may begin in the eyes before it reaches speech or deed.

To look daggers means glare with intense anger or hostility. The idiom turns eyes into weapons, making sight itself capable of wounding. In poetry, it is useful for silent conflict, jealousy, social tension, family quarrels, or suppressed rage. Students should notice how it differs from spoken anger: the violence remains visual and unspoken. It pairs well with blades, glances, mirrors, eyebrows, and rooms heavy with silence.
