Other forms: lineaments
A lineament is a fancy, literary word that means "a part of a person's face," like his eyes, ears, or nose.
In his poem "Manfred", Lord Byron wrote, "She was like me in lineaments — her eyes / Her hair, her features, all..." He was basically saying that a particular woman's face looked a lot like his own face, when he examined each part of it — each lineament — separately. The word comes from the Latin word linea, meaning "line." Lineaments can also refer to someone's distinctive features, not just their looks.
