- spasm:  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 *spə- ‘stretch’. The metaphorical notion of ‘intermittence’ (based on the intervals between spasms) emerged in the derived adjective spasmodic  in the 19th century.
