身體內部的合拍
核心畫面最小的版本：被排進同一個次序的，是同一個人身上的眼睛、手和腳。
noun · B2
The way the different parts of your body work together while you move, so that your eyes, hands and feet each do the right thing at the right moment; also how well you can do this.
協調性；肢體協調
核心畫面
Picture several parts that are all fine on their own, and someone putting them into one order so they move on the same beat. Eye, hand and foot do it inside one body. Three teams do it across one festival. Two sentences do it side by side with and. In every case nothing is added and nothing is ranked above the rest — only the order and the timing are set.
可以想成好幾個部分，各自都沒問題，然後有人把它們排進同一個次序裡，讓它們照同一個拍子動。在一個人身上，是眼睛、手、腳…更多收起
可以想成好幾個部分，各自都沒問題，然後有人把它們排進同一個次序裡，讓它們照同一個拍子動。在一個人身上，是眼睛、手、腳。在一場活動裡，是三個組別。在一個句子裡，是被 and 接起來的兩段話。共同點是：沒有多加東西，也沒有誰壓在誰上面，被排好的只是先後和時間。From the word’s history
The supplied Wiktionary entry traces the word to Late Latin coordinatio, from con- (together) plus ordinatio (an ordering). That is the modern core almost word for word: putting things into one order together.
packet 裡的 Wiktionary 記錄寫得很清楚：這個字來自晚期拉丁文 coōrdinātiō，由 con-（一起）加上 ōrdinātiō（排序）組成。字面幾乎就是今天的核心：把幾樣東西一起擺進同一個次序。
Wiktionary entry supplied in this packet (source_ref kaikki:3f6f69a190036ae4:644342559): From Middle French coordination, from Late Latin coōrdinātiōnem, from con- + ōrdinātiō.
Three branches
人與單位之間的統籌
同一個畫面放大：要排進同一個次序的不再是肌肉，而是人、組別、機構。撞期和重工，就是組織版的「手慢了半拍」。
noun · B2
The work of making separate people, groups or parts act together in the right order, so that they help each other instead of repeating the same job or getting in each other's way; also the state of working together well that this produces.
協調；統籌
文法上的對等並列
核心裡「誰也不壓在誰上面」那一點，在文法裡被拿來當專門術語：用 and、or、but 接起來的兩段話地位相等，跟被塞進別句裡的從屬子句不同。
noun · C1
In grammar, the joining of two or more words, phrases or sentences that have equal weight, using a word such as and, or or but.
