Descriptive Text“It was an arresting face, pointed of chin, square of jaw. Her eyes were pale green without a touch of hazel, starred with bristly black lashes and slightly tilted at the ends. Above them, her thick black brows slanted upward, cutting a startling oblique line in her magnolia-white skin–that skin so prized by Southern women and so carefully guarded with bonnets, veils and mittens against hot Georgia suns”

Scarlett O’Hara described in Gone with the Wind.

Learning from Descriptive Text

Visually descriptive language provides:• Information about the world, especially the visual world.• information about how people construct natural language for

imagery.• guidance for visual recognition. How do people

describe the world?
