Misuse is a subset of word choice. It’s not that there’s a better similar word. You’ve just picked the wrong word. Try to do better; your copy will improve.
Ironic/Ironically for Unusual or Coincidental
Probably, the most wrongly cast, misused word in contemporary English is “ironic” when the writer or speaker actually means “unusual” or “conicidental” rather than its true meaning: saying the opposite of what you really mean.
According to Merriam-Webster, irony “is the use of words to express something other than and especially the opposite of the literal meaning; a usually humorous or sardonic literary style or form characterized by irony.”
Unfortunately, this mistake is so prevalent that even great writers like F. Scott Fitzgerald, who we assume chose his words carefully, have succumbed to society’s rampant misuse of the word. Ironic is misused everywhere, from literature to mundane news stories, for example an article from SFGate: “’Which is kind of ironic because that’s usually a drier spot,’ Gass said.”
