I just reread (it had been a few years) Alphagene’s link to Cecil’s column on “The Bronx.” Historical accident or not, the term “The Bronx” is formally codified in the legislation that named the borough. Some background…
As Cecil points out, when NYC first expanded beyond Manhattan Island (1874) it annexed a chunk of lower Westchester County, west of the Bronx River. This was called variously “the 23rd and 24th Wards,” “the North Side” and “the Annexed District.” (I have never heard Cecil’s phrase “the Annexed District of the Bronx,” but no matter.)
In 1895, the 24th Ward of NYC was expanded to include more of lower Westchester Co., this time the portion east of the Bronx River.
In 1897 the NY State legislature passed the Greater New York Charter which consolidated Kings County (coextensive with the City of Brooklyn), Richmond County (Staten Island), and the western third of Queens County into the City of New York – then consisting of Manhattan Island and all of the Annexed District. That’s when the borough names were officially born.
I quote from the charter:
“Division into Boroughs.
SEC.2 The City of New York, as constituted by this Act, is hereby divided into five Boroughs to be designated respectively: Manhattan, The Bronx, Brooklyn, Queens and Richmond; the boundaries whereof shall be as follows: …”
Everywhere “Bronx” is mentioned it is preceded by “The,” even in phrases like “…the Borough of The Bronx…”; the first “the” is lower case, and the second “The” is capped.
Thus, it is “The Bronx,” complete with an upper case “T.”
Argyle: (I said it was an inside joke, but you asked, so…) The not-so-great neighborhood in NYC you’re thinking of is Bedford-Stuyvesant.
Stuyvesant is a high school in Manhattan that is the perennial rival of Bronx Science; both are specialized math-science public (yes, free) schools that admit students strictly on the basis of entrance exam scores. SHS – which has a higher score requirement than BS – is often described as the best high school in the country, a statement based on test scores, SAT’s, Westinghouse/Intel Award winners, Ivy League admissions, etc…
Stuyvesant’s reputation has lately spread beyond NYC and the academic world via Pulitzer Prize author Frank McCourt (“Angela’s Ashes,” “'Tis”) who taught there and refers to the school and its students in his books. It’s alumni include countless movers and shakers in various fields, but mostly scientists and doctors, including one astronaut and at least one Nobel Prize winner. And, oh yeah, James Cagney graduated from there too.
