Think of a manner as the way a person does a thing, watched from outside: how they hand you the plate, how they say your name, how they hold themselves when others are in the room. Adding -ed makes the word say that this way of doing things is noticeable — the person carries a manner. From there, everything depends on one question: is that manner there for the people in the room, or for the look of it? Put well or bad in front and you are judging how the person treats others. Leave the word alone and you are saying the manner has taken over, and what you see is the doing rather than the person.
From the word’s history
The word is manner plus -ed and goes back to Middle English manered, so its parts already say it: carrying a manner.
這個字是 manner（做事、待人的方式）加上 -ed 組成的，可以追到中古英語的 manered。字的組成本身就把核心說完了：帶著某種方式的。
