Medical researchers recommend learning something new each day is good for your brain. J.J. and I employ an easy, painless way for us to learn something new everyday. It's free app for iPhone and called Word of the Day!
The daily word is shown with pronunciation guide, parts of speech, meaning as well as its use in a sentence. If you are already familiar with the word, you swipe the screen and get an alternate one.
For example, today's word is:
Abscond. Alternates are Slugabed and Irascible.
While reading books and online articles are excellent ways to improve and expand one's vocabulary, this direct approach is another terrific way to learn and keep your brain in tiptop shape.
