English is a funny language. But I like it. English is tough to master. But it offers immense opportunities for thought and expression. Thinking clearly without language is almost impossible. Rather, language is a precondition for logical thought. Without a rich language, thinking will remain limited. English being the richest language enables the most complex thoughts and expression.

English was not always so rich. It ‘became’ rich. It picked up words from various other languages, vernaculars and cultures. If a good number of people were using a particular word, the English language adopted it and gladly included the word into its lexicon. That is why using ‘prepone’ for ‘advance’ is correct English today. It was not so about a few months ago.

The lesson to learn from English language is that, enrichment is possible only when one tries to ‘become’ and not ‘be’.
