vaporosity

Vaporosity is an uncommon noun meaning the state or quality of being vaporous, especially of consisting of or containing vapor. In literal use, it denotes a gaseous or steam-like condition. The word is transparent despite its rarity because it is formed directly from “vapor” and the suffix “-ity,” and it is close in sense to “vaporousness” or “vaporiness.” It should not be confused with “porosity,” which refers to the presence of tiny spaces or pores through which fluid can pass, not to a vaporous condition. The adjective “vaporous” can also be used figuratively for something vague or insubstantial, but “vaporosity” is most safely understood in its literal, physical sense. In everyday English, however, “vaporousness,” “gaseous,” or simply a more specific description is usually clearer and more idiomatic. Vaporosity is chiefly notable as a precise, uncommon label for a condition that common words handle only approximately.

Etymology of vaporosity

Vaporosity was formed in English from “vapor” and the noun-forming suffix “-ity.” The word “vapor” came through Middle English from Old French and ultimately from the Latin vapor, meaning “steam” or “vapor.” Words such as “vaporous,” “vaporize,” and “evaporation” reflect the same Latin root, while the suffix “-ity” turns the adjective “vaporous” into an abstract noun.

How vaporosity is actually used

Rare and often perceived as literary or old-fashioned. In modern prose, “vaporousness” or a more specific term will usually sound more natural.
