contracti onとは 意味・読み方・使い方

語源

From Late 中期英語 contraccioun, contraxion (“spasm, contraction; constriction, shrinking; act of pressing together”), from Old French contraction (modern French contraction), from Latin contractiō(n) (“a drawing together, contraction; abridgement, shortening; dejection, despondency”), from contrahō (“to draw things together, assemble, collect, gather; to enter into a contract”) + -tiō(n) (suffix forming nouns relating to actions or their results). Contrahō is derived from con- (prefix denoting a bringing together of objects) + trahō (“to drag, pull”) (probably from Proto-Indo-European *dʰregʰ- (“to drag, pull; to run”)). By surface analysis, contract +‎ -ion (suffix denoting actions or processes, or their results).

      • 2020 April 8, David Turner, “How Railway Staff were Conduits and Victims of a Pandemic”, in Rail, Peterborough, Cambridgeshire: Bauer Media, →ISSN, →OCLC, page 32:

        Railway workers were therefore a perfect subject for research, given the varied roles they undertook. If infection was greatest among the non-public-facing staff, it would suggest – given most worked outside – that contraction was caused by something found in the "atmosphere at large". If affliction was higher among the indoor and public-facing staff, it would suggest that human contact was the cause. And it was the latter point that was proven.
