Extensive exposure to good quality English via “reading & listening” is a surefire way to improve vocabulary. Here’s an activity to learn how to carry out an intensive study of words—form, meaning, use, collocation, association, etc. Use an authentic dictionary and try to understand each and every word / word combination in the following paragraph. Do share your discoveries with others.
“Pirates are daring, adventurous, and willing to set forth into uncharted territories with no guarantee of success. They reject the status quo and refuse to conform to any society that stifles creativity and independence. They are entrepreneurs who take risks and are willing to travel to the ends of the earth for that which they value. Although fiercely independent, they travel with and embrace a diverse crew. If you’re willing to live by the code, commit to the voyage, and pull your share of the load, then you’re free to set sail. Pirates don’t much care about public perception; they proudly fly their flags in defiance. And besides, everybody loves a pirate.”
