Lethargy. It's a word I know, because it's in one of my father's favorite expressions. Lethargy breeds lethargy. It means the more you lie around doing nothing, the more you want to lie around doing nothing. Your limbs and your mind feel so heavy that it becomes a major effort just to lift your arm to channel surf.
One of the really bad things you can do to your writing is to dress up the vocabulary, looking for long words because you're maybe a little bit ashamed of your short ones. This is like dressing up a household pet in evening clothes. The pet is embarrassed and the person who committed this act of premeditated cuteness should be even more embarrassed.
Metaphor isn't just decorative language. If it were, it wouldn't scare us so much. . . . Colorful language threatens some people, who associate it, I think, with a kind of eroticism (playing with language in public = playing with yourself), and with extra expense (having to sense or feel more). I don't share that opinion. Why reduce life to a monotone? Is that truer to the experience of being alive? I don't think so. It robs us of life's many textures. Language provides an abundance of words to keep us company on our travels. But we're losing words at a reckless pace, the national vocabulary is shrinking. Most Americans use only several hundred words or so. Frugality has its place, but not in the larder of language. We rely on words to help us detail how we feel, what we once felt, what we can feel. When the blood drains out of language, one's experience of life weakens and grows pale. It's not simply a dumbing down, but a numbing.
A man with a scant vocabulary will almost certainly be a weak thinker. The richer and more copious one's vocabulary and the greater one's awareness of fine distinctions and subtle nuances of meaning, the more fertile and precise is likely to be one's thinking. Knowledge of things and knowledge of the words for them grow together. If you do not know the words, you can hardly know the thing.
Every one has experienced how learning an appropriate name for what was dim and vague cleared up and crystallized the whole matter. Some meaning seems distinct almost within reach, but is elusive; it refuses to condense into definite form; the attaching of a word somehow (just how, it is almost impossible to say) puts limits around the meaning, draws it out from the void, makes it stand out as an entity on its own account.
