Manhattan's many neighborhoods are not named according to any particular convention. Some are geographical (the Upper East Side), or ethnically descriptive (Little Italy). Others are acronyms, such as TriBeCa (for "TRIangle BElow CAnal Street") or SoHo ("SOuth of HOuston"), or the far more recent vintages NoLIta ("NOrth of Little ITAly"). and NoMad ("NOrth of MADison Square Park"). Harlem is a name from the Dutch colonial era after Haarlem, a city in the Netherlands. Alphabet City comprises Avenues A, B, C, and D, to which its name refers. Some have simple folkloric names, such as Hell's Kitchen, alongside their more official but lesser used title (in this case, Clinton).
