Vocabulary Improving - and Not by Improvisation

Why and Way to Improve Our Vocabulary.
Why?
Because great person has great range of vocabulary. Every words has its own context. And the more vocabulary we know, the better can we explain our thought.
Way?
1.Be Aware of Words
- Be aware especially with words whom you're familiar with but still don't know what its real meaning is.
- Don't only read, try to look for words of interest to us for further study whenever and wherever we may meet them. Even though it may slow down our reading progress, but it eventually will make us better in understanding the whole story.

2.Read
Because the applicable place for our vocabulary is mostly in reading. Read things that we're interested with, and read, don't just look. Read as often as possible and also always keep in mind the idea of learning new words.

3.Use a Dictionary
-Have our own dictionary. A small one is alright.
-Circle the words we look up. Whenever we open our dictionary, of course our eye will naturally move to the circled words. This can give some kind of a review for us.
-Read the entire entry for word you look up. Some words have many meanings, especially, context. Don't just look at the first word given by our dictionary, read the whole part.

4. Once I Actually Didn't Know The Meaning of This Word!
Keep on reviewing. Give a spare amount of special time for vocabulary learning. It can be reviewing, or learning new ones. Keep on doing it and be systematic about studying so we can be sure that we really do progress. We can use Index card in which each word is placed in one card. And we'll soon see that our vocabulary cards grow thicker and thicker :))
