Definitions

1. To cause a plant or organism to become pale or weakened by depriving it of light or essential nutrients, leading to reduced vitality and altered coloration
2. Inducing a condition in living organisms characterized by paleness or diminished strength due to lack of natural light or necessary elements; often resulting in stunted growth or abnormal appearance
3. The process of making vegetation or biological material pale or feeble by limiting exposure to light and vital substances, often causing decreased robustness and altered development

Etymology: A seedling grown in the dark turns pale and spindly, and the word for that condition comes from the image of stubble. Its ancestor is Latin "stipula," meaning straw or stalk. Old French turned this into "estieule," the short stems left standing in a field after harvest, and French speakers then formed "étioler" from it, applying the picture to plants that had grown white and weak. English took the idea as "etiolate." The original image is still visible in the botanical sense: a plant starved of light stretches, bleaches, and goes limp, much like the dry stalks it was compared to. The figurative sense of looking pale and drained comes from the same picture.

Synonyms: etiolate, blanch, pale, bleach, whiten
