Etymology
Origin of indigestible
From the Late Latin word indīgestibilis, dating back to 1520–30. See in- 3, digestible
Explanation
If you've ever eaten something that your body couldn't break down and absorb, it was indigestible. Certain edible but indigestible substances are essential for maintaining a healthy digestive system. Many healthy plant foods are full of indigestible matter called dietary fiber. Our bodies lack the enzymes needed to fully break it down. This indigestible bulk helps move food through the digestive system and supports the growth of beneficial bacteria in the gut. The term now also figuratively describes information or concepts that are very difficult, or impossible, to understand or "absorb" mentally — such as the dense jargon in legal documents.
