The action of depriving someone; the act of taking something away.
From deprive + -ment (suffix forming nouns that indicate an action or result). This is another variant formation alongside deprivation, showing how English word-building can create synonyms.
Deprivement is even rarer than deprival—it's a byproduct of English's generous word-building system that allows multiple forms (-ment, -ation, -al) on the same root, but only some become popular enough to survive.
