Synonyms are words you use when you can’t spell the first one. Okay, that’s just a joke”¦or a quip”¦or a wisecrack”¦or a jest, jive, or jape. But I think you get my point.


Synonyms allow us never to be at a loss for words. If you know your synonyms, you are not only richer for it, but it also gives you the odds when it comes to word games like crosswords 7 Quick Tools to Help You Solve Crossword Puzzles Online Read More and Scrabble.

    Great article with a few resources I was not aware of and want to check out. I am a writer (mostly grant writing and advocacy) and I tend to use the same words frequently and want to increase my vocabulary.

      For me the problem isn't the learning. It is the remembering. So, as a promise to myself, I try to use a new word in my next article or in any online conversation.

    Synonymy, as the introduction to Webster's Dictionary of Synonyms, is the study of the differences between words with similar meanings---that is, in order to select precisely the correct word from a pile of words that are close in meaning.

    It's a good list especially for people whos English isn't the first language. I'm writing some stuff in english and many times have that "writers glitch" with not finding sufficient word.

      Precisely, you have hit the nail on the head with what these are meant to do.

    Maybe the author should have used a 'Synonym Dictionary' to discover that it is called a Thesaurus.

      I don't need to because I do know it is called that. But in web writing we have to pitch an article (with the title) in a way that addresses the greatest common denominator of readers and the way they are searching for something. The term 'dictionary' outscores 'thesaurus' and is more common than the latter. Not everybody is a word pundit and that's why it's better to go with more common terms. To assuage your criticism, I have used 'thesaurus' quite a few times.
