viscousness

Resistance to flow

Viscousness is the quality of being viscous—thick, sticky, and resistant to flow.

It describes liquids like honey, syrup, or motor oil that move sluggishly rather than freely.

The term overlaps with viscosity, though viscosity is more common in technical contexts where precise measurement matters.

The viscousness of the batter made it hard to pour.
