Expression is the dress of thought, and
Appears more decent as more suitable;
A vile conceit in pompous words expressed,
Is like a clown in regal purple dressed. [ Pope ]

These papers of the day have uses more adequate to the purposes of common life than more pompous and durable volumes. [ Dr. Johnson ]

Any one may mouth out a passage with a theatrical cadence, or get upon stilts to tell his thoughts; but to write or speak with propriety and simplicity is a more difficult task. Thus it is easy to affect a pompous style, to use a word twice as big as the thing you want to express; it is not so easy to pitch upon the very word that exactly fits it. [ Hazlitt ]
