A new feature of all of the corpora as of October 2009 is the "random word" function. As you click on "RANDOM", it will find a random word from the top 20,0000 lemmas (headwords) in the corpus and then insert this into the search form. This is a great way to just kind of browse through the corpus and find new and interesting words.

By default, it will display the words belonging to that lemma (e.g. twirl, twirling, etc for the lemma twirl), and you can then click on these to see them in context. It might be more useful, however, to use:

    -- CHART displays to see the frequency of the random word in the different sections of the corpus
    -- CONTEXT, to see collocates of the random word (and thus insights into its meaning and use), or
    -- SYNONYMS, to see other words related to the random word (maybe select [SECTIONS] = [SHOW] as well)

To use any of these three, just make sure that you do one of the three types of searches above before you start your "random searches". For example, mysterious in CHARTS, CONTEXT, OR SYNONYMS (click these to run, and then click on [RANDOM] for more words).
