@neo-anchorite,
Socrato,
You are not alone in your in your question of "why must we use big words." Zentetic hits the nail on the head when he says that "big words mean big ideas in fewer words." To a point you have to use those big words to explain those complex ideas, otherwise you get into an even more complex form of description. Most if not every word in the dictionary was at one time complex notions and ideas that ultimately became a single conceptual word. Look at the etymology (root of the word) of
definition for example.
Defintion comes from the latin
Dei fini, which means "to make finite." The notion of
"to make finite" ultimately stems from the Greek word
horos meaning "land marker" which would
"limit, or boundry." Now if I didn't use the big word
defintion, I would instead be saying, "the limited, or boundary, or finiteness, or land marker of (x) is (x). But we say definition because it encapsulates those ideas.
So if you think about it, you use big words every day, you have just grown accustomed to the universal context. Big words from
histology to
pseudo ciliated squamous epithelium are familiar and essential to Aedes for example because he uses words like those in his profession. But could you imagine using an extrapolated version of
pseudo ciliated squamous epithelium? It's even in cases like those that he may use Acronyms because even simplified definitions are too long, like the example "AIDS" instead of Auto Immune Deficiency syndrome. Zentetic would operate in that way with mathematics, Theaetetus with music, etc,etc,etc.
But that is where I think you, socrato, deliver your well placed point. Why can't people in general speak in a simplified way? It is either that these words are relatively comprehensive (as I explained previously), or people intentionally use difficult composition to convey their ideas to sound profound. There is a saying that, "stupid people use big words to make themselves sound smart." This is sometimes true. There have been more than a few times I have encountered people on the forum who have used big words for the sake of using big words, and in the process lose all cogency in their argument. So I agree with your sentiments in some respects.
