英語の語源
spasm
spasm: [14] A spasm is etymologically a sudden ‘stretching’ of a muscle (although in fact physiologically spasms are contractions of muscle tissue). The word comes via Old French spasme and Latin spasmus from Greek spasmós, a derivative of the verb span ‘pull’. This in turn was descended from the Indo-European base *sp?- ‘stretch’. The metaphorical notion of ‘intermittence’ (based on the intervals between spasms) emerged in the derived adjective spasmodic [17] in the 19th century. => stadium
