What Are the 12 Words Only the Top 5% Know?
Below is a list of words that separate the truly well-read from the rest. But this isn’t just academic trivia, these words have real-world applications, particularly in high-pressure business situations.
- Perspicacious: Having keen insight or understanding. Example in business: “I admire her perspicacious ability to identify untapped market opportunities.”
- Pusillanimous: Showing a lack of courage or determination. Use it when describing hesitant competitors: “Their pusillanimous strategy left the market wide open for us.”
- Sanguine: Optimistic or positive, especially in difficult situations. A perfect term for leadership in a crisis: “His sanguine outlook kept the team motivated through challenging months.”
- Ebullient: Overflowing with enthusiasm or energy. Think of how you’d describe a dynamic pitch: “Her ebullient pitch helped secure the VC funding.”
- Esoteric: Understood by a small, specialized audience. Use in marketing strategy discussions: “This campaign might be too esoteric for a general audience.”
- Ineffable: Too great or extreme to be expressed in words. Applicable in branding: “The ineffable joy of using this product is central to its appeal.”
- Quotidian: Ordinary or occurring every day. A productivity tip: “Our focus should be on improving quotidian workflows before tackling speculative projects.”
- Mendacious: Dishonest or deceitful. Use when addressing transparency issues: “We can’t afford a mendacious brand reputation.”
- Obstreperous: Noisy and difficult to control. Useful when discussing team dynamics: “We need a strategy to manage obstreperous stakeholders without escalating tensions.”
- Magnanimous: Generous or forgiving, especially toward a rival. Relevant in partnerships: “Let’s take a magnanimous approach during these negotiations to maintain goodwill.”
- Recalcitrant: Stubbornly uncooperative. Ideal for describing internal challenges: “The project faced delays due to recalcitrant team members resistant to change.”
- Perfidious: Betraying trust; treacherous. Use this word cautiously but powerfully: “Unfortunately, their perfidious actions led us to reconsider the partnership.”
How Can You Remember and Use These Words?
Feeling daunted? Don’t be. Growing your vocabulary doesn’t have to be tedious. Here are practical tips:
- Use Context to Memorize: Instead of rote memorization, plug these words into your everyday life. For instance, discuss “sanguine” when talking about economic outlooks.

- Practice Regularly: Commit to using one new word a week in conversations, emails, or meetings.
- Leverage Technology: Use apps like Vocabulary.com to track and quiz yourself on new words.

Common Mistakes to Avoid
- Overusing Complex Words: Nobody wants to feel like they’re in an SAT prep class during a meeting. Use wisely and sparingly.
- Using Words Incorrectly: Learn the nuances. For example, “perfidious” carries an emotional weight unlike milder synonyms like “untrustworthy.”
- Aiming for Quantity Over Quality: It’s better to master a handful of impactful words than to misuse many.
- Neglecting Context: This ensures you’re not applying a word where it doesn’t fit, making you sound out of touch.
