LEXICOGRAPHER, n. A pestilent fellow who, under the pretense of recording some particular stage in the development of a language, does what he can to arrest its growth, stiffen its flexibility and mechanize its methods.
OBSOLETE, adj. No longer used by the timid. Said chiefly of words. A word which some lexicographer has marked obsolete is ever thereafter an object of dread and loathing to the fool writer . . .
The bold and discerning writer who, recognizing the truth that language must grow by innovation if it grow at all, makes new words and uses the old in an unfamiliar sense has no following and is tartly reminded that 'it isn't in the dictionary' - although down to the time of the first lexicographer no author ever had used a word that was in the dictionary.
