Etymology: "Porositas" is a Latin noun meaning the quality of being porous, formed from "porus" (a passage or opening, a pore) with the abstract suffix "-itas," which turns an adjective into a noun of state, as in "bonitas" (goodness) or "utilitas" (usefulness). The Latin "porus" came from Greek "poros," meaning a passage, ford, or opening, and that Greek word is related to "poros" in the sense of a way across, which makes the underlying idea of a route through something. The English word "porosity" is the direct descendant of this Latin form and follows the same pattern, with the Latin ending replaced by the English "-ity." Like many scientific terms, "porosity" was adopted into English in the early modern period, when writers in natural philosophy needed precise vocabulary for materials with small openings.
