核心畫面
One way to hold this word: picture a number going up on a board, and then ask who is standing next to it. Two different people can be. One made the number move — she put the ball in, or she answered the questions right. The other wrote the number down so that it counts. English gives both of them the same name, because -er only says "the one involved in scoring"; it does not say which side of the number they stand on. The sentence around the word tells you which: points belong to a scorer who plays, a sheet and a pen belong to a scorer who records.

可以想成記分板上的數字往上跳，然後問一句：旁邊站的是誰？答案有兩種人。一種是讓那個數字動起來的人——球進了，或者題目答對了。另一種是把數字寫下來、讓它算數的人。英文給這兩種人同一個名字。因為 -er 只說「跟 score 這件事有關的那一個」，沒有說他站在數字的哪一邊。真正告訴你的是句子：講到球、分數、賽季，是上場的人；講到記分表、核對，是記錄的人。From the word’s history
Wiktionary derives scorer from score + -er, tracing the ending back through Middle English -ere to Old English -ere, the ending that names the one who does something.
Wiktionary 記錄 scorer 是 score 加 -er，並把這個字尾一路追到中古英語 -ere、古英語 -ere，也就是「做這件事的人」。這正好解釋了為什麼一個字能同時是得分的人和記分的人——字尾只說「有份」，沒說是哪一種份。
