VOCABULARY:
There are three basic questions arise in the mind about the vocabulary,
1. How does it play an important role in our daily reading?
2. Why does one need vocabulary?
3. How does that make journey of reading comfortable?

Most obvious questions are those when you generally think about vocabulary. So, let us take an example of the following sentences, I am pretty sure that they will definitely clear: what I want to convey...
- A girl has a philemaphobia; that's why she refuses to come closer to her beau.
-Due to having a philemaphobia, girl doesn't want to kiss her beau.
-Philemaphobia means fear of kiss.

Now, observe carefully above three sentences. The first sentence is vague; what the sentence want to convey you can't get it. In the second sentence, you've got quasi-idea of it. In the third sentence everything is crystal clear(I've chosen this word deliberately to express most effectively what is the meaning of vocabulary & how it is useful to us). Such kinds of words, you will rarely encounter while reading but they do really exist.
