英文词源
- sporadic
- sporadic: [17] Sporadic means etymologically ‘scattered like seed’. It comes via medieval Latin sporadicus from Greek sporadikós, a derivative of the adjective sporás ‘scattered’. This was formed from the same base as produced sporá ‘act of sowing, seed’, ancestor of English diaspora [19] (etymologically ‘dispersal’) and spore [19]. And both were related to speírein ‘sow’, source of English sperm.
=> diaspora, sperm, spore - sporadic (adj.)
- 1680s, from Medieval Latin sporadicus "scattered," from Greek sporadikos "scattered," from sporas (genitive sporados) "scattered, dispersed," from spora "a sowing" (see spore). Originally a medical term, "occurring in scattered instances;" the meaning "happening at intervals" is first recorded 1847. Related: Sporadical (1650s); sporadically.
