Usage Notes

  • "Prescribe is a much commoner word and means either 'issue a medical prescription' or 'recommend with authority,' as in the doctor prescribed antibiotics. Proscribe, on the other hand, is a formal word meaning 'condemn or forbid,' as in gambling was strictly proscribed by the authorities."
    (Maurice Waite, ed., Oxford Thesaurus of English, 3rd ed. Oxford University Press, 2009)
  • "These are almost direct opposites, and ought not to be confused. To prescribe is to define a remedy, to ordain, to decree. To proscribe is to prohibit, to forbid, to ban. When the Food and Drug Administration proscribed Laetrile, it meant that no doctor could lawfully prescribe it."
    (James J. Kilpatrick, The Writer's Art. Andrews McMeel, 1984)
