federation 可以想成好幾個原本各自獨立的團體，在一份共同的約定下把手牽在一起，合成一個更大的整體，但各自還保有自己的樣子。From the word’s history
From Latin foedus (genitive foederis) "covenant, league, treaty": a federation is parts bound into one by a shared pact—the agreement is what holds them together.
字根 foedus（屬格 foederis）在拉丁文是「盟約、聯盟、條約」；federation 的核心比較像靠一紙共同的約定，把各個部分綁成一個整體——真正把大家綁在一起的，是那份約定。
