Usage
What does dreadful mean? Dreadful most commonly means extremely bad, unpleasant, or ugly. Less commonly, it can also mean causing great fear or terror, which makes sense because dreadful is the adjective form of the noun dread, meaning fear. Dreadful can also be used as an intensifier (a word that makes the meaning of the word it modifies more intense) in much the same way that awful can, as in You took a dreadful long time getting time. In cases like this, neither awful nor dreadful mean bad, but they are typically used in negative situations as opposed to positive ones. Dreadful can also be used in a more specific way as a shortened form of the term penny dreadful, the name for inexpensive illustrated books featuring violent action that were popular in Britain during the mid- and late-1800s. Example: My throat hurts, my head’s pounding, I’ve got the chills—I feel absolutely dreadful.

Explanation
Something that's terribly bad is dreadful. Some people love going to the opera, but for others there's no more dreadful way to spend three hours. Dreadful means "full of dread," "feeling a sense of dread," or "causing dread." Dread means fear or anxiety. The adjective dreadful can describe something truly devastating, like the dreadful aftermath of a tornado, or something that's awful on a more personal level, like a dreadful blind date. If it's bad, fearsome, or unpleasant, you can call it dreadful.
