Make the longest sentece you can using words that start with the same letter and follow as many grammatical rules as you can. Repeat this for every letter in the alphabet, yes including Q and Z though they won't be very long.

After a while, you'll find yourself using words you never though you knew.

Don't get frustrates and keep at it, use a dictionary and thesaurus if you have some time.

That will increase anyone's vocabulary.

Here's another way of increasing word usage:

In your daily writing practice (journal, log entry, scrabble, sentence games) Write the same sentence as many different ways as you can... keep the implied meaning the same, but don't reuse any of the words (if you can help it).

In his book, "On Writing", King mentions not trying to forcibly increase your vocab, as your writing will show that you're trying to show off all of your new words.

In a fiction book I read as a child, I remember one of the characters saying something I thought was rather wise, that a word isn't "yours" till you've used it three times naturally in conversation--not purposely, but when it just "comes out."

That said, I still wonder why writers are always being told to expand their vocabularies and then admonished not to use big words when small ones will do.

One of my pet peeves is the lowering of the grade levels of books. It seems to me that if the publishing industry keeps pandering to an ever more infantile audience--reading level-wise--it's working itself out of a job. How soon before Dick and Jane invade Asimov and "I Robot" becomes "I am a Robot. I can walk and run"?

To me, the industry should be lifting the bar or at least keeping it in place. If a reader must consult a dictionary once in a while or deduce the meaning of a word from its context, so be it.

One of the best examples of this comes from Louise Cooper; don't know if she does this in all of her books, but in her series of books about Indigo, the heroine never ever ever had a problem. She always, exclusively had concondrums. Perfectly valid word, but damn! And this character never referred to a problem as a problem; "I have a concondrum... This is a mighty confusing concondrum." Who uses this word?

LOL. Anyway, sometimes simpler is better... a nickel word MAY be as effective as a word worth a dime, you know?

Thus, I recommend the following:

1. Pry $20 from your parsimonious palms and purchase Verbal Advantage by Charles Harrington Elster from Amazon.com and spend six months reading and rereading it.

2. Read broadly: read philosophy, theology, history, and literature. This is the best way to learn how to use words correctly, and how to use them with elegance.

3. Read with a dictionary. You can't always discern the meaning of a word from its context. For example, if you were to read, "After her exciting night on the town, she felt enervated," do you know what enervated means? If not, guess and then look it up.

By the way, if you haven’t read Brideshead Revisited by Evelyn Waugh, you haven’t lived.
