    the everyday word for scattered broken pieces, with no scientific limit on the cause

  • tephra

用法筆記

Ejecta is a Latin plural and normally works as a mass noun: in scientific writing it takes a plural verb ('the ejecta were dated to 1815') and has no separate '-s' plural form.

常見錯誤

❌The volcano spat out three ejectas.
✅The volcano spat out a huge amount of ejecta.
💡'ejecta' is already a plural form, so it never takes an '-s' and is not counted as 'one ejecta, two ejectas'.

同義詞
  • discharge

    a more general term for matter released from the body, not only vomit

  • vomit

    specifically the matter brought up from the stomach through the mouth

用法筆記

Mainly a clinical or old-fashioned medical term; everyday speakers say 'vomit' or 'what someone brought up' rather than this group word. Distinguish from sense 1, which is matter thrown out by volcanoes or explosions, not by the body.
