dictionary of difficult words

I found a book called the Dictionary of Difficult Words in my friend’s truck, there is such a book.  I didn’t open it.  I know what a lot of them are already.  Committed, cheated, rejected, obligated, shame, guilt, repent….reciprocal (good Lord).  These words have to be in there.  Committed for example.  Does this mean determined to stick with your decision?  Or does it mean sentenced to a mental hospital, imprisoned?  And if you commit to a thing that becomes hellish and you go crazy, like if you are in a bad friendship or marriage, does it mean both things?  There are so many difficult words to be honest.  But I’d really like to see the Dictionary of Wonderful Words instead.  I can guess a bunch of those too.  Familiar,      enough,      curious,    launch,     exhale,     subtle and supple,     quiet,     content,     conscious…all wonderful.  It would be good to have both books – they should sell them in a set.

Do you have a difficult or wonderful word to add?  Please let me know.
