For the Love of Words

I know a few people who keep quote books, but does anyone out there keep track of your favorite words?  In the red journal I wrote of yesterday, I've saved several pages in the back for just that.  I'm not exactly sure why I like these more than others.  It might be merely how they roll off my tongue, or perhaps because of an interesting etymology.  Here are a few of my faves:

osculate ~ to kiss: a pretentious or facetious usage

puckish ~ impish or whimsical  (Guess the back story on this one.)

undulant ~ rising and falling in waves OR having a wavy form, outline, or surface

wonky ~ shaky, feeble, unreliable

ennui ~ a feeling of weariness and dissatisfaction: boredom

sedulous ~ involving or accomplished with careful perseverance; diligent in application or pursuit

embonpoint ~ plumpness of person (but not excessively overweight)

schwarmerei ~ excessive or unwholesome sentiment

rime ~ frost

potboiler ~ a usually inferior work--as of art or literature--produced chiefly for profit  (The back story here is that it was either so overproduced or so inferior, or both, that its best use was for the fire under the soup pot.)

nepenthe ~ a potion used by the ancients to induce forgetfulness of pain or sorrow OR something capable of causing oblivion of grief or suffering

There are some words which I loathe as well, but I don't dignify them by recording them in a journal.  I'll write a few here though: slacks, blouse, and cancer.

Which words do you love/hate?
