Etymology

Origin of gluten

First recorded in 1590–1600, gluten is from the Latin word glūten glue

Explanation

Gluten is a protein that's found in some grains, such as wheat. It's the gluten in wheat that makes bread dough strong and stretchy. If you've ever kneaded dough for cinnamon rolls, or stretched pizza dough into a large circle, you know how elastic the combination of yeast, sugar, flour, and water comes to feel. People who are allergic or sensitive to gluten avoid eating grains that contain it, but those who aren't bothered by gluten enjoy the chewy texture of homemade wheat bread. In Latin, gluten means "glue."
