What does viscosity mean?
The measure of a fluid's resistance to flow; the degree to which a fluid resists flow when an external force is applied. The higher the viscosity, the thicker and more resistant to flow the fluid is.
Example
"The viscosity of the oil in the engine was too high, causing it to overheat."
