How to prepare for synonyms?

The best way to prepare for synonyms is that we must make sure that we attempt to improve our vocabulary through reading. We may read novels, the newspaper or any other English literature media especially the Classics. Most nationally circulated newspapers contain articles written in a decent level of language. This helps by letting us build context surrounding the words. When we see the word being used in a sentence, you form a background on the word, making it easier to guess its synonym.
