As a reader, you can use it like you would normally use a dictionary, to look up specialized or unusual words, and you'll get what you expect: a concise definition to get you back to reading.
But... here's the great part. As a writer, you can also use it to look up words you already know. Or think you do! And you should, because this is Mr. Webster's actual and original dictionary. The real deal.
The magic is in the definitions for commonplace words. Just take a look at the screenshots! This is good stuff. It will delight and amuse. It may even kindle your imagination.
The author's personality shines through in colorful prose that's packed with classic examples of usage.
Remember paging through a big hardcover dictionary looking for a word only to get sidetracked exploring other words you'd stumble across?
Oh-hoh! If I may bend your ear a moment longer...
The usual way to do search is to show only results that match what has been typed so far. And normally that's perfect: don't show you anything you don't need to see, right?
But if I did it that way, how can you get sidetracked?
So I went a different direction. All of the words are in a giant list. You can scroll through all the words. And as you search, it scrolls to the first match. It's fast and you can find what you want quickly, but it still leaves room for serendipity.
It's good. It's free. It's solid. It's not junked up with ads.
Get it and get writing!
