Learn English – difference between “plagiarizer” and “plagiarist”

differencesword-usage

Dictionary.com lists plagiarist as the noun form of plagiarism and lists plagiarizer as the noun form of plagiarize. I do not see the distinction of the separate entries and expected both words to be listed as noun forms.

There are many1 -ist/-izer pairs in which one could imagine some difference in meaning between them, such as in (perhaps) at least some of these pairs:

  • agonist, agonizer
  • Americanist, Americanizer
  • antagonist, antagonizer
  • apologist, apologizer
  • baptist, baptizer
  • botanist, botanizer
  • dramatist, dramatizer
  • economist, economizer
  • generalist, generalizer
  • hypnotist, hypnotizer
  • Ionist, ionizer
  • journalist, journalizer
  • localist, localizer
  • maximist, maximizer
  • minimist, minimizer
  • modernist, modernizer
  • monopolist, monopolizer
  • moralist, moralizer
  • naturalist, naturalizer
  • novelist, novelizer
  • optimist, optimizer
  • pluralist, pluralizer
  • psychologist, psychologizer
  • realist, realizer
  • secularist, secularizer
  • terrorist, terrorizer
  • theorist, theorizer

However, it turns out that in this particular case, the OED defines both to be exactly the same:

plagiarizer = plagiarist


1. There being something like 154 such -ist/-izer pairs in the OED. This is a little under half the total number of -izer words (323), but only a very small portion of the total number of -ist words therein attested (3,774).
