7 Common Words That Mean the Exact Opposite of What You Think

Have you ever confidently used a word, only to discover later that its meaning was entirely different from what you believed? If so, you’re not alone! The English language is rife with such words that can lead to misunderstandings in everyday conversation. In this post, we will explore some of the most commonly misused words, clearing up their true meanings. Whether you’re a language enthusiast or simply looking to enhance your communication skills, this list will help you express yourself more clearly and confidently. Let’s dive in!
1. Outlaw
People often think it means: Someone who has broken the law.
But it really means: A person excluded from the protection of the law.
Historically, Robin Hood is labeled an outlaw not just for stealing from the rich, but because he has been stripped of all legal rights. This means anyone, including the Sheriff of Nottingham, could harm him without facing legal consequences. As unfortunate as it may sound, spending time with in-laws might actually be the safer option!
2. Factoid
People often think it means: A fun, trivial fact.
But it really means: A fun, FALSE fact.
First coined by Norman Mailer in 1973, the term “factoid” referred to information fabricated by gossip journalists. The suffix “-oid” implies something resembling a fact but not being one. To share a genuine tidbit, consider using “fun fact” instead.
3. Scan
People often think it means: To skim.
But it really means: To thoroughly examine something point by point.
Originally from a 14th-century term meaning “to count off metric feet” in poetry, scan’s meaning evolved by the 1920s to imply a more cursory glance—possibly influenced by factory robots designed for speed.
4. Nonplussed
People often think it means: Undisturbed.
But it really means: Utterly baffled.
For generations, this word has caused confusion. Many mistakenly interpret it as “unfazed,” when it actually denotes a state of bewilderment. The Latin phrase non plus means “no more,” implying that one has reached a point where they can neither think nor act further.
5. Enervated
People often think it means: Energized.
But it really means: Weakened.
Originally, the term nerve referred to ligaments and tendons, but by the 1600s, it evolved to signify strength. Conversely, to “enervate” meant to sever or weaken, and today it carries the sense of diminishing vitality.
6. Inflammable
People often think it means: Not flammable.
But it really means: Totally super flammable.
The prefix “in-” can convey two different meanings. In the case of “inflammable”—which predates “flammable”—it means something that can easily catch fire, leading to potentially dangerous misinterpretations. That’s why warning signs often feature striking images of flames.
7. Irregardless
People often think it means: Regardless.
But it really means: With regard, or nothing at all.
Irregardless is a contentious term often criticized by grammar purists. The prefix “ir-” means “not,” while the suffix “-less” means “without,” so it literally means “not without regard.” This contradicts its intended meaning, which leads many to advocate for its removal from our vocabulary, yet it remains in popular use, irregardless of the backlash.
