Big words and improper phraseology are prison bars that sometimes separate the worker from the professional people.

"Stone walls do not a prison make," because the human mind can get beyond them.

But thick-shelled words do make a prison.

They are something that the human mind can not penetrate.
A man whose skill is in his hands can puddle a two hundred-pound ball of iron.

A man whose skill is on his tongue can juggle four-syllable words.
But that iron puddler could not savvy four-syllable words any more than the word juggler could puddle a heat of iron.
