What does compulsoriness mean?
Compulsoriness is an abstract noun denoting the quality of being compulsory — that is, required by law, regulation, or established rule rather than left to individual choice. Where the adjective "compulsory" describes a thing as mandatory, "compulsoriness" names that mandatory character itself, allowing writers to discuss obligation as a property or concept. It appears chiefly in formal registers: legal analysis, educational policy debates, and administrative writing, where phrases like "the compulsoriness of attendance rules" or "the compulsoriness of military service" occasionally surface. The word derives from "compulsory," which traces back through Late Latin compulsorius to the Latin verb compellere, "to drive or force together." Because English speakers typically paraphrase — saying "the fact that X is compulsory" — compulsoriness remains uncommon, giving it a distinctly bureaucratic, scholarly flavour. Its natural opposites are optionality and voluntariness: what is not compulsory is, in principle, a matter of free choice.
nounThe quality or state of being compulsory; the fact of being required by rule or law rather than left optional.
- The state or quality of being required by law, rule, or authority rather than optional.
"The compulsoriness of military service in that country has been debated for decades."
"Parents questioned the compulsoriness of school uniforms at the board meeting."
"The report examined the compulsoriness of voting in several democratic systems."
Almost never used in the plural; the plural form exists grammatically but is essentially unattested outside contrived contexts.
"Different jurisdictions attach differing compulsorinesses to their education laws — though even here, most writers would rephrase."
Every time someone says a subject is 'compulsory', they're invoking this word's meaning without ever using the word itself — compulsoriness is the hidden noun behind one of English's most familiar adjectives.

Etymology of compulsoriness
Compulsoriness was formed within English by attaching the native suffix -ness to the adjective compulsory, creating an abstract noun for the quality of being mandated. Compulsory itself comes from Medieval Latin compulsorius, derived from Latin compellere (com-, "together," plus pellere, "to drive"), the same root that gives English compel, compulsion, expel, and propel. The adjective entered English around the early seventeenth century, and the noun followed later as legal and administrative prose demanded a way to talk about obligatoriness as a concept.
