Did You Know?

Unlike most English terms with Latin parentage, mutatis mutandis (which translates literally as "things having been changed that have to be changed") maintains its Latinate aspect entirely. It doesn't look like an English phrase, which is perhaps why it remains rather uncommon despite having functioned in English since the 16th century. Although the phrase is used in the specialized fields of law, philosophy, and economics when analogous situations are discussed, it appears in other contexts, too, where analogy occurs, as this quote from Henry James' The American demonstrates: "Roderick made an admirable bust of her at the beginning of the winter, and a dozen women came rushing to him to be done, mutatis mutandis, in the same style."
