A definite description is a denoting phrase in the form of "the X" where X is a noun-phrase or a singular common noun. The definite description is proper if X applies to a unique individual or object. For example: "the first person in space" and "the 42nd President of the United States of America", are proper. The definite descriptions "the person in space" and "the Senator from Ohio" are improper because the noun phrase X applies to more than one thing, and the definite descriptions "the first man on Mars" and "the Senator from Washington D.C." are improper because X applies to nothing. Improper descriptions raise some difficult questions about the law of excluded middle, denotation, modality, and mental content.

Famous quotes containing the words definite and/or description:
“Slowly, and in spite of anything we Americans do or do not do, it looks a little as if you and some other good people are going to have to answer the old question of whether you want to keep your country unshackled by taking even more definite steps to do so—even firing shots—or, on the other hand, submitting to be shackled for the sake of not losing one American life.”
—Franklin D. Roosevelt (1882–1945)
“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
—Henry David Thoreau (1817–1862)
