Usage note[edit]

The senses of "dreadful" synonymous with "afraid" similarly use the infinitive or the preposition "of": they were dreadful to build or the boy was dreadful of his majesty. These senses are, however, now obsolete.

When used as an intensifier, "dreadful" is actually an ungrammatical form of the adverb "dreadfully" and thus considered informal or vulgar.




dreadful ‎(plural dreadfuls)

  1. A shocker: a report of a crime written in a provokingly lurid style.
  2. A journal or broadsheet printing such reports.
  3. A shocking or sensational crime.(Can we verify(+) this sense?)
