The state or result of being separated or cut apart; a forceful division.
From dissever + -ment (noun suffix). The -ment suffix, from Old French -ment and Latin -mentum, typically marks the result or outcome of an action, prominent in English since the 13th century.
Words ending in -ment often describe the result or aftermath of something—'punishment' is what happens after you're punished, 'movement' is the result of moving. It's past-tense thinking baked into the word form.
