The action of separating or cutting apart; complete division or severance.
From Latin disseveratio or directly from dis- + sever + -ation. The -ation suffix (from Latin -atio) creates nouns of action and is extremely productive in English for scholarly and technical terms.
The -ation suffix is the heavyweight champion of English noun-making—it appears in thousands of words and signals technical or formal language. Words ending in -ation often sound more official, which is why legal documents love them.
