One of the really bad things you can do to your writing is to dress up the vocabulary, looking for long words because you're maybe a little bit ashamed of your short ones. This is like dressing up a household pet in evening clothes. The pet is embarrassed and the person who committed this act of premeditated cuteness should be even more embarrassed.
We are losing our common vocabulary, built over thousands of years to help and delight and instruct us, for the sake of what we take to be the new technology's virtues.
"Right!" "Right!" "You can get there!" "I can get there!" "You're a natural at counting to two!" "I'm a nat'ral at counting to two!" "If you can count to two, you can count to anything!" "If I can count to two, I can count to anything!" "And then the world is your mollusc!" "My mollusc! What's a mollusc?"
There was a language specific to all things. The ability to learn another language in one arena, whether it was music, medicine, or finance, could be used to accelerate learning and other arenas, too.
Human vocabulary is still not capable, and probably never will be, of knowing, recognizing, and communicating everything that can be humanly experienced and felt. Some say that the main cause of this very serious difficulty lies in the fact that human beings are basically made of clay, which, as the encyclopedias helpfully explain, is a detrital sedimentary rock made up of tiny mineral fragments measuring one two hundred and fifty-sixths of a millimeter. Until now, despite long linguistic study, no one has managed to come up with a name for this.
A good vocabulary is not acquired by reading books written according to some notion of the vocabulary of one's age group. It comes from reading books above one.
In so-called primitive societies there are two words for power, mana and taboo: the power which creates and the power which destroys; the power which is benign and the power which is malign. Odd that we have retained in our vocabulary the word for dangerous power, taboo, and have lost mana.
