被召集之後的那場大會
核心畫面裡通知寄出之後的那一幕：人真的坐進同一個廳裡了。

正式大會
核心畫面
Picture a letter going out to a long list of people, all of whom have to come. Someone with the authority to do it has fixed a day and a hall, and on that day people travel in from everywhere and sit down in one room. That is the whole picture: not people deciding to meet, but people being called. Every use of convocation keeps some part of it — sometimes the meeting that results, sometimes the act of calling itself, sometimes the last day a university calls its students together, and once, in older writing, a sky full of eagles gathered as if summoned.

可以想成一封通知寄了出去，名單很長，而名單上的人都得到場。有權力的人定了日子、訂了場地；到了那天，大家從各地趕來，坐進同一個廳裡。整個畫面的重點在這裡：不是大家自己約好要見面，而是有人被叫來。convocation 的每個意思都留著這張畫面的一部分——有時是被叫來以後的那場會議，有時是「叫」這個動作本身，有時是大學最後一次把學生叫到一起的那一天。還有一個少見的用法，把滿天像是被召集過來的老鷹也叫作 a convocation。From the word’s history
The supplied source traces convocation through Middle English convocacioun and Old French from Latin convocatio, convocationem. The Latin noun is from the same family as voice and vocal, so the idea of calling sits inside the word rather than being added to it later.
本次證據裡的 Wiktionary 記載：convocation 經由中古英文 convocacioun 和古法文，來自拉丁文 convocatio／convocationem。那個拉丁字跟 voice、vocal、invoke 可以想成同一家人，核心都繞著「叫、發聲」。所以「把人叫到一起」不是後來加上去的意思，它本來就在字裡面。

「叫人到一起」這個動作本身
把鏡頭往前拉到會議之前：通知還在寄，場地還在訂，人還沒到。
noun · C1
The act of calling people together for a large formal meeting, and the work of arranging it. This use is formal and uncountable, so it has no plural and takes no a.
召集
學校最後一次把大家叫到一起
大學把畢業生、老師和家人正式召集起來的那一天；還是同一個動作，只是這一次是為了收尾。
noun · C1
In American English, the formal ceremony held at a college or university when students have finished their studies and are leaving. Usually countable and usually singular.
畢業典禮
借去講鳥：一群老鷹
英文的動物群名常常挑一個有畫面的字；老鷹拿到的是這一個，像是滿天的大鳥被召集過來。
noun · C2
A group of eagles. English gives some animals their own group word, and this is the one used for eagles. It is rare and belongs mostly to written and literary English.
