I don't mean to be gasconading, but I was pretty proud of writing an entire post yesterday using only one syllable words. And I couldn't even say that is what I was doing because "syllable" has more than one syllable.
Words can be a challenge. Having been trained in Journalism, I was taught never to use a $20 word when a ten cent one would suffice. Communication is difficult enough without trying to dazzle people with lots of syllables. But I have to admit that only being able to use one-syllable words gets boring. You also can't use many adjectives when you are confined to one syllable.
BTW, the longest word in an English language dictionary is pneumonoultramicroscopicsilicovolcanoconiosis, a lung disease. The longest non-technical word in an English language dictionary is floccinaucinihilipilification. It refers to the act of estimating something as worthless. There is a certain irony there.
