The book begins with an anecdote about the OED updating its entry for “marriage” when the (British) marriage equality act was passed, and how this was framed in the press as participating in a “change of definition”. This is followed by an anecdote from a slander case in 1942, which argued that “lesbian” could not be slanderous, as it was (incorrectly) asserted that the word didn’t exist in English when the relevant law was passed--an argument based on citations in the OED entry for “lesbian”, which was not included in the first edition published in 1908.
