What does vacuity mean?
Vacuity denotes emptiness, especially an absence of thought, ideas, or meaningful content. It is usually used in formal or literary criticism to characterize speeches, writing, institutions, or arguments that sound substantial but communicate little. The word can be dismissive: calling something vacuous suggests not merely that it is uninformative, but that its apparent importance conceals an intellectual or moral emptiness. In a second, more formal sense, vacuity can mean the condition of being empty or unoccupied, though this use is less common in modern English. Because it names a particularly abstract kind of emptiness—one of ideas rather than simply a space—vacuity has a sharp, faintly literary tone. It is useful when discussing rhetoric that has been emptied of substance, while being too forceful for neutral description. The noun is more often treated as a mass noun than as something with regular plurals, although “vacuities” is possible when referring to individual empty statements or effects.

Where does vacuity come from?
Vacuity entered English in the early 17th century from Latin vacuitas, meaning “emptiness.” The Latin noun was formed from vacuus, “empty,” which in turn came from vacare, “to be empty.” The same root underlies words such as vacant, vacancy, vacuous, and vacate.
