I have found Merriam-Webster.com to be a great place to look up definitions of words and to listen to proper pronunciations. And recently, thanks to the advice of a colleague (thank you, Jacki!), I discovered Merriam-Webster offers even more online. Here's a list of other helpful features you can find on Merriam-Webster's Website:
• Videos - Wondering what the plural of octopus is? How about the difference between rein and reign? Merriam-Webster offers clear, concise videos on a variety of topics (and they're interesting to watch!).
• Trend Watch - If you want to learn about words that have been top lookups recently on Merriam-Webster.com check out their Trend Watch page. For example, on August 11 one of the top lookups was rancor thanks to the jurors in the trial of former Illinois Governor Rod Blagojevich. They used it in their note to the judge.
• New Words & Slang - This is Merriam-Webster's collection of user-submitted words. It's where words go before they make it into the dictionary.
So whether you simply love words, want to improve your grammar and spelling, or need to submit a word for dictionary consideration, Merriam-Webster.com has something for you.
