[word net 3.0 word senses appear in a table below]

Note: that no sentence parsing word part of speech detection is used in the
following examples -- thus every word that might be a noun is treated as a
noun here.  This produces non-sense in some cases, though you can see that
the sentence might be reworded to make the verb be a noun and then can
see what the s/w would have done with it.  In the example below, note that
the word "left" is mistakenly interpreted as the past tense of "leave".
