What is the difference between “horrify” and “terrify”?

Since I am not a native English speaker, I always have trouble figuring out when to use "horrible" instead of "terrible" in both spoken and written English.

According to American Heritage Dictionary, Horrible means:

adj. Arousing or tending to arouse horror; dreadful: "War is beyond all words horrible” (Winston S. Churchill).
adj. Very unpleasant; disagreeable.

and Terrible means:

adj. Causing great fear or alarm; dreadful: a terrible bolt of lightning; a terrible curse.
adj. Extremely formidable: terrible responsibilities.
adj. Extreme in extent or degree; intense: "the life for which he had paid so terrible a price” (Leslie Fiedler).
adj. Unpleasant; disagreeable: had a terrible time at the party; terrible food.
adj. Very bad: a terrible actor.

Since their secondary meaning is Unpleasant, disagreeable, are there any rules around when these words should be used, or can they be used interchangeably?


In everyday informal discourse, spoken or written, the words are interchangeable: neither means much of anything beyond "very bad". If someone says to you "Bob's presentation was terrible" you may with perfect propriety respond "Yeah, really horrible."

In more careful usage the two words bear very different different meanings. These reflect the respective first definitions you quote from AHD; see also the discussion of the associated verb forms at the link provided by ЯegDwight in his comment to your question. Briefly:

  • horrible speaks to the sense of outrage which an act or event arouses: the act transgresses ordinary rational or natural or moral boundaries. Hitler's final solution and Lovecraft's Ancient Ones are horrible.
  • terrible speaks to the sense of dread which an act or event arouses: the act is a sign or a warning of what may come to pass. Tamerlane's conquests and the Lisbon Earthquake of 1755 are terrible.

Of course an act or event may be both horrible and terrible; but the words address different aspects.
