Watford是 a real town一個真實存在的城鎮, just north-west of London就在倫敦西北邊, at the edge of where the city's commuter belt begins位在倫敦通勤圈開始的邊緣. But但 the reason it is in a learner's dictionary它會出現在學習者字典裡的原因 is the joke phrase "north of Watford"是玩笑話north of Watford (also "Watford Gap")（也叫Watford Gap）

When a Londoner says "north of Watford", they do not mean geography. They mean: out there, far away, a place I know nothing about and secretly think does not matter.

So所以 the phrase is really about London, not about the North這句話講的其實是倫敦，而不是北部

Someone from Manchester or Leeds may use it sharply, to point at that narrowness: "As usual, the government forgets anything north of Watford." That second use has real feeling in it — a long-standing complaint that money and attention stay in the south.
