It's embarrassing when you pause in the midst of writing and speaking, since you can't think of the right word. The idea is clear in your mind and the word with the exact shade of meaning is right on the tip of your tongue, but it stays there when you use a poor substitute and turn to the pages of dictionary (for a right word). It happens so, because you can't afford to overlook the power of words to make your communication effective as the word power is the world power. Hence, the management of language needs a rich vocabulary and the profound source of words is Synonyms and Antonyms.
