One way to hold it: a single line drawn between you and the north, with an arrow on it. Sometimes you are the thing travelling up that line, or sitting at the far top of it. Sometimes something else is coming down it towards you — and that is the wind. Same line every time; only the traffic on it changes.
可以想成你跟北方之間有一條線，上面畫了一個箭頭。有時候是你自己沿著這條線往上走，或者坐在這條線最上頭的位置。有時候是別的東西沿著這條線往下來找你——那就是風。線一直是同一條，變的只是誰在上面移動。
From the word’s history
From norther + -ly. The ending -ly here means having to do with, not the adverb -ly, which is why the word can serve as adjective, noun and adverb without changing shape.
由 norther（北）加上 -ly 造成。這裡的 -ly 是「跟…有關的」，不是副詞的那個 -ly。也因為這樣，同一個形狀可以當形容詞、名詞和副詞。
