Common Mistakes When Using Terrible Synonyms

1. Using “terribly” as an adjective. “Terribly” is an adverb meaning “very” — “terribly sorry” is correct, but “a terribly meal” is wrong. The adjective you want is “terrible” or one of its synonyms. Grammarly’s guide to synonyms is a handy reminder that word form matters as much as word choice.
2. Firing “atrocious” at small faults. A slightly late bus is not atrocious. If your strongest word fires at every pebble, it has nothing left for boulders.
3. Mixing up “dreadful” and “dreaded”. “Dreadful” describes how bad something is; “dreaded” describes something feared before it happens — “the dreaded exam” was feared, and it may have turned out dreadful too.
4. Writing “lousy” or “rotten” in a formal complaint. Both are vivid but informal. A complaint letter lands harder with “poor”, “unacceptable”, or “appalling”.
