There is no wijk (Dutch for "district") that exists in both London and New York with only 4 letters.
Here's why:
- London: While London has many districts with 4 letters (Soho, Peck, Earl's Court, etc.), none of these are commonly known as "wijken" as the Dutch term wouldn't be used in this context.
- New York City: Similarly, New York City boroughs (Manhattan, Brooklyn, Queens, etc.) wouldn't be referred to as "wijken" and have more than 4 letters. Neighborhoods within these boroughs often have more than 4 letters as well (SoHo, Tribeca, Harlem, etc.).
There might be a possibility of a very specific nickname for a district in both cities that uses 4 letters, but it's highly unlikely and wouldn't be a common term.
