As any custom is disused, the words that expressed it must perish with it; as any opinion grows popular, it will innovate speech in the same proportion as it alters practice.
Samuel JohnsonWhen a language begins to teem with books, it is tending to refinement; as those who undertake to teach others must have undergone some labour in improving themselves, they set a proportionate value on their own thoughts, and wish to enforce them by efficacious expressions; speech becomes embodied and permanent; different modes and phrases are compared, and the best obtains an establishment. By degrees one age improves upon another.
Samuel Johnson
