Note: Troy and I recommend only products that we have tried and tested. These include the popular vocabulary-improvement software Ultimate Vocabulary.*
These emails come once a day, and each one will give you a generally less commonly used word to add to your vocabulary. The email includes a pronunciation guide, a definition, some examples of the word in use, and some etymological information too (the origins and development of the word over time).
Here is a short list of some of the more popular services out there; see which one you like and give it a try. The challenge we set for you is to use the daily word at least five times that day — that will really get the new word into your ever-growing vocabulary!
• Dictionary.com > Word of the Day
• Merriam-Webster > Word of the Day
• Oxford English Dictionary > Word of the Day (the subscription link is in the right-hand side bar)
• The Free Dictionary > Word of the Day
• Wordsmith > A.Word.A.Day
If you want to increase your vocabulary even more quickly, then try using the popular program Ultimate Vocabulary!
