词源

From Latin comminūtiō (“breaking into pieces, crumbling, shattering; crushing, pulverizing”), from Latin comminuō (“to break or crumble into small pieces; to crush, pulverize”) (from com- (prefix indicating completeness) + minuō (“to make smaller; to diminish, lessen”), ultimately from Proto-Indo-European *mey- (“little, small”)) + Latin -tiō (suffix forming a noun relating to some action or the result of an action); equivalent to comminute + -ion.
