Definition: Viscosity is a measurement of how resistant a fluid is to attempts to move through it. A fluid with a low viscosity is said to be thin, while a high viscosity fluid is said to be thick.. It is easier to move through a low viscosity fluid (like water) than a high viscosity fluid (like honey).
The term 'viscosity' describes a material's property from a physicist's point of view. It is a fluid's thickness. Scientifically speaking, it is the measure of a fluid's internal flow resistance, the resistance to being deformed. The two-plates model mathematically describes this definition. A fluid's viscosity is determined by viscometry, which is part of a wider science called rheometry. Rheometry again is part of rheology, the science of materials' flow behavior and deformation. All materials range on an imaginary scale from solid to liquid.
