expedient 可以想成一隻卡住的腳，還有把它拔出來最快的那個動作。這個字講的是「眼前先脫身」。它不保證你脫身以後走的方向是對的，只說這一招現在有用。正因為它對是非保持沉默，用起來常常帶著一點陰影：讀者會自動聽出「所以代價呢？」這個字的形容詞和名詞，差別只在你是在形容那個做法，還是直接把那個做法叫出名字。From the word’s history
The packet's Wiktionary etymology derives it from Latin expedire, from ex ('out') plus pes ('foot') — literally freeing the foot. That picture still fits the modern core: the move that gets you out of the immediate difficulty.
封包裡的 Wiktionary 字源寫著：這個字來自拉丁文 expedire，由 ex（出來）加上 pēs（腳）組成，字面像是「把腳拔出來」。這張圖跟今天的核心意思正好合得上——先脫困再說。要注意這是字源的線索，不是說現代人用這個字時真的想到腳。
