Definitions

Etymology: "Inseparableness" is simply "inseparable" with the suffix "-ness" attached, the suffix that turns an adjective into a noun naming a quality. "Inseparable" itself comes from Latin "inseparabilis", built from the negative prefix "in-", "separabilis" ("capable of being separated"), and the verb "separare" ("to separate"), so the word is a layered construction: Latin roots, filtered through Middle English adjective formation, with an English noun ending added last. The result names a state rather than a thing. Where "inseparable" describes two or more things that cannot be parted, "inseparableness" lets you talk about that unbreakable quality as if it were an object in its own right, as in discussing the inseparableness of mind and body. English has a large family of such pairs, and this one is a plain, transparent formation with no surprises hidden in its history.
