Famous quotes containing the word usage:

    “...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
    —Kenneth G. Wilson (b. 1923)
