As a matter of the English language, “the” is a definite article. Dictionary.com explains that “the” is “used, especially before a noun, with a specifying or particularizing effect, as opposed to the indefinite or generalizing force of the indefinite article a or an.”
Of course, any graduate or fan of The Ohio State University knows that “THE” is used with “a specifying or particularizing effect.” And, as of this week, so does the rest of the world–because this week the U.S. Patent and Trademark Office registered “THE” as a trademark of the Ohio State University when that word is used on branded products associated with and sold through athletics and collegiate channels. That recognition reflects the efforts and emphasis of the many Ohio State athletes who have identified their alma mater as “THE Ohio State University” on sports broadcasts.
I think it is great that Ohio State has successfully registered “THE” as a trademark for THE University, because it bugs the crap out of other schools–like TTUN. Let those other schools stumble along with their indefinite articles or prepositions! Ohio State may not win the national championship, or even the Big Ten, every year, but we’ll always be “THE.”
