【中文词源】：

来自拉丁语 spasmus,来自希腊语 spasmos,痉挛，抽搐，来自 PIE*spe,拉长，拉伸，词源同 span,spade,-asm,名词后缀。

【英语词源】：

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 [17] in the 19th century.
