Definition

A characteristic of certain substances that allows them to become more liquid when stirred or shaken, and then return to a thicker state when left still.

Example

The paint showed thixotropy, making it easy to apply but thickening when left in the can.

Conversation

Have you ever heard about thixotropy?

No, what is that?

It's this cool property where certain gels become fluid when you stir them.

That sounds interesting! I didn't know gels could act like that.

Root Explanation

Thixotropy is formed from "thixis" (from Greek 'thixis', meaning touch or to touch) and "tropia" (from Greek 'tropos', meaning turning or change). The word describes a property of certain gels or fluids that become less viscous when agitated or touched, indicating a change in their state due to mechanical stress.

Memory Tip

Think of 'touching' ('thixis') something that causes it to 'change' ('tropos') its consistency — that's why thixotropy refers to materials that change viscosity when stirred.
