  • Lexicography is a science of making dictionaries.

  • This word was chosen as Wordnik word of the day.

  • A fine usage right here.

  • And I was just going to do a quick wordie check and start cleaning my house.... Hmmmmm. Where to begin? I think I'll start with l*:slacker.

    BTW: Look at the word of the day today on OneLook!

  • Thanks pterodactyl, I wasn't aware of the tool you mentioned. I'm keen to check it out ... there goes the weekend!

    February 27, 2009

  • Ditto, ptero. I now use OneLook more than any of the other online dictionaries.

    February 27, 2009

  • My favorite online dictionary, OneLook, offers not only wildcards but also a "search by meaning" tool (the colon). For example, if you wanted to find words that start with M and mean "smooth", you could go to OneLook and type in "m*:smooth". It's useful not only for finding spellings but also for finding words you don't know.

    I first discovered OneLook by way of Wordie, so let me just pause and say a hearty "Thanks, John!".

  • Oooh! Bonus points for using the word maunderings. I like finding examples of words that you won't find in thesauruses even though their synonyms are listed.

    February 27, 2009

  • I've always admired bilby's mollifluous maunderings.

    February 27, 2009

  • Some online dictionaries offer wildcard searches. So if you think mellifluous is spelled a certain way you can type in mal* and see what happens. The results show maliciousness then malign so it's clear it doesn't start with mal-. Then you'd try mel* (as it's the only other vowel that sounds about right) and you'd be on your way.

  • Very funny, Fox. Maybe s/he was being facetious, but I suspect the latter.

  • Website idea: ditchonary.net?

    February 27, 2009

  • TBT, you would probably have some idea about how the word is spelled, wouldn't you? Often the problematic part of the word comes in the middle or the end (e.g. -able or -ible, -ant or -ent), so you know enough to look the word up and discover the correct spelling. If the word starts in a quirky way, like the name of our friend pterodactyl, then you might indeed be stumped, but after a while you may even start recognizing some of these deceptive spellings, and know that if the word isn't spelled one way then it is probably spelled another way. Most people, I suspect, use dictionaries to confirm or correct spellings they think they know.

    February 27, 2009

  • I never understood why a dictionary is considered good for learning the correct way to spell a word. If I don't know how the word is spelled, how can I look it up in the dictionary?

    February 27, 2009

  • Oh, wow!

    February 26, 2009

  • Like Wordie, but with photos. :-)

  • dictionary.com now has *free* auditory pronunciation. I'm not too dismayed to learn that I've been mispronouncing the s-word.

  • Another fun fact:

    Modern English is rooted almost equally in Latin, French and Germanic. The percentages, provided by Oxford Dictionaries, are below:

    Latin, including modern scientific and technical Latin: 28.24%
    French, including Old French and early Anglo-French: 28.3%
    Old and Middle English, Old Norse, and Dutch: 25%
    Greek: 5.32%
    No etymology given: 4.03%
    Derived from proper names: 3.28%
    All other languages contributed less than 1%

  • Fun Fact about English:

    There are somewhere between 450,000 and 600,000 unique words in the various English dictionaries (OED, MW).
