词汇 | sine qua non |
词源 | sine qua non. That which is indispensable, an indispensable condition, something essential. Although the words translate as “without which nothing,” the original Latin phrase from which they were taken is Sine qua non potest esse, “Without which it is not possible to exist.” Dating back in English use to the 16th century, the words have their origins in Aristotelian expressions. The term is also used attributively (“Publication is a sine qua non condition for the generation of literature”—Tho- mas De Quincey, Works, 1860) and can be used to mean “some- body indispensable.” The little-known plural, sine quibus non, is not used in the humorous expression for men’s trousers— “these indispensables” being called sine qua nons. |
