Why not follow this to its logical conclusion?

  Remove all synonyms
  Example: fine -> good

  Remove antonyms and just negate the word
  Example: bad -> ungood

  Remove special-case nouns: just combine a noun and one or more adjectives to reach the same meaning with fewer fundamental words.
  Example: great -> doubleplusgood; murder -> collateral damage

We could call this doubleplusgood language newspeak.
