數字在跑：漲得比另一邊快
把賽跑的畫面從兩個人搬到兩條往上走的線。花的錢跑在賺的錢前面，需求跑在供應前面。沒有人真的在動，但「拉開距離、追不上」這個核心動作一模一樣，而拉開的那個缺口就是問題所在。

If one thing outruns another, it grows or rises faster than the other one can keep up with, so the second one is left short or behind.

核心畫面
Picture two runners side by side. Outrun is the moment one of them pulls ahead and the gap starts to open — not just moving fast, but moving fast enough to leave the other one behind.

可以把 outrun 想成兩個人並排在跑。其中一個慢慢拉開距離，後面那個追不上了。out- 在這裡像是「在這件事上贏過你」，run 則是比的項目。所以整個字的畫面可以想成：跑這一項，我贏你。而且常常還多一層結果——他已經追不到我了。英文還有一整排這樣造的字，像 outplay、outsell，拆法都一樣。From the word’s history
The source traces the word simply to out- + run. It does not gloss the prefix, so the reading of out- as beating the other side on that activity is offered as a model built from the pattern (outplay, outsell), not as a translation from the source.
來源資料只把這個字拆成 out- 加 run，沒有替 out- 下定義。所以「out- = 在這件事上贏過對方」是從 outplay、outsell 這一排字歸納出來的看法，是一個好用的想法，不是資料上寫的字義。
