分享想法這件事與這個能力
這一組最貼近字根「使其共有」：人與人之間把資訊、想法、感受傳過去的這件事本身，以及把它做得清楚的那份能力。

核心畫面
You can picture something passing across the gap between people so that it becomes shared — an idea, a feeling, a message moving from one mind to another until both hold it.

可以想成有個東西越過人與人之間的縫隙，傳過去而成為共有的——一個想法、一種感受、一則訊息從一個腦袋移到另一個腦袋，直到兩邊都握有它。communication 的每個用法都是這個「傳過去」的某種版本：動作本身、承載它的管道、做得好的能力、或被送出去的那則訊息。From the word’s history
Communication comes from Latin 'communicare' = 'to make common, share', from 'communis' (common, shared). So at root it means making something common between people — which is exactly the picture of an idea passing across until both sides share it.
communication 源自拉丁文 communicare，意思是「使其共有、分享」，來自 communis（共有的、公共的）。所以它的根本意思就是讓某樣東西在人與人之間變成共有——正好就是「想法傳過去、直到兩邊都共有」這個畫面。

承載訊息的系統與管道
