What does lubricity mean?
Lubricity is a formal noun meaning smoothness or slipperiness, especially the quality of a substance that reduces friction between moving surfaces. It is especially associated with oils, greases, and other lubricants, as in a discussion of a material's lubricity or its suitability for machinery. The word can also describe the ease with which an activity, negotiation, or process moves forward without difficulty. In technical and clinical writing, lubricity may refer to the quality of facilitating sexual intercourse. Although the word has a technical sound, its underlying idea is simple: it names the absence of friction. In everyday language, smoothness or ease usually serves more directly, but lubricity is useful when precision is important or when referring to the physical property that allows surfaces, mechanisms, or processes to operate more easily.
