unctuosity

Hummus owes much of its unctuosity to rich tahini—sesame paste.

Reduced to powder, the softness and unctuosity of steatite have caused it to be used, in the same manner as plumbago, for lubricating purposes, and when finely ground it is employed for giving a surface to some kinds of paperhangings.

“What I might have expected from my noble compatriot!” exclaimed the Dictator with greasy unctuosity; “I was sure of it.”

The Ligaments, the Tendons, and the Cartilages have scarce any of the Unctuosity left, which render’d them so supple and so pliant in Youth.

This same sulphurous Unctuosity at the same time spreads itself in the solid Parts, and gives them, in some sense, their natural Suppleness; it bestows on the Membranes, the Tendons, the Ligaments, and the Cartilages, a kind of Oil which renders them smooth and flexible.
