Investors, Beware the Sesquipedalian Language Trap
In the world of finance, clear communication is a currency as valuable as cash. A single misunderstood phrase can move markets. This makes today’s word of the day, sesquipedalian, more than just a vocabulary exercise. It is a critical warning for every investor.
What Does Sesquipedalian Mean?
The term sesquipedalian has two related meanings. Literally, it describes a very long word, often one that is polysyllabic. More commonly, it characterizes a style of speaking or writing that uses overly long and complex words. A sesquipedalian speaker prefers “utilize” over “use” and “ameliorate” over “improve.” They might describe a problem as a “multifaceted exigency” rather than a “complex emergency.”
This tendency toward linguistic ornamentation is not just about word length. It is about the deliberate choice of obscure, technical, or needlessly complex language where simpler terms would do. In finance, this practice can be a significant red flag.
Why It Matters for Your Portfolio
For investors, the elasticity of language that sesquipedalian words represent can be dangerous. Corporate earnings reports, regulatory filings, and executive statements should aim for transparency. When language is “stretched” or “embellished” with jargon, it can obscure reality rather than reveal it.
Consider a company’s annual report. A clear statement might read, “Sales fell due to lower customer demand.” A sesquipedalian version could obfuscate: “Revenue streams experienced a contractionary phase precipitated by attenuated consumer engagement metrics.” The second version sounds more impressive, but it hides the simple, troubling truth.
This practice is not limited to bad news. Startups and new ventures may use complex, technical language to make a simple business model seem revolutionary. Cryptocurrency whitepapers and some fintech pitches have been historically prone to this, using a barrage of buzzwords to create an aura of sophistication that may mask a lack of substance.
The Power of Plain English
Just as language can be stretched, it can also be “compressed or stripped bare.” This is the antidote. Legendary investor Warren Buffett is famous for insisting that Berkshire Hathaway’s annual reports be written so his sisters can understand them. He champions plain English as a sign of honest communication.
When an executive, fund manager, or analyst explains a concept in simple terms, it often signals deep understanding and confidence. They are not hiding behind a veil of vocabulary. As an investor, you should view clear, concise communication as a positive indicator of management’s clarity of thought and respect for shareholders.
Your task is to become a critical listener. When you encounter sesquipedalian language in an investment context, pause. Ask yourself what simple truth is being wrapped in complex words. Is it to clarify a genuinely complex idea, or is it to confuse? The difference could protect your capital. In the markets, where information is power, the clearest message is often the most powerful one.
