A schemer is a person who, in secret, makes clever plans that are not honest, so they can get what they want. The word already judges the person: you would not call a friend a schemer unless you were angry or warning someone. Writers and newspapers use it for people who work behind other people’s backs.

A schemer陰謀家 is a person who就是 in secret私底下, makes clever plans想一些聰明計謀 that are not honest卻不老實, so they can get what they want好得到自己想要的東西。The word這個字 already judges the person已經帶著評價, you would not call a friend a schemer你不會叫朋友schemer, unless you were angry or warning someone除非你在生氣或警告別人。Writers and newspapers作家和報紙 use it for people用這個字來稱呼 who work behind other people's backs在別人背後搞小動作的人。

Though actually, the shorter word scheme is milder in British English — a “pension scheme” or a “colour scheme” has no dishonesty in it at all. The person-word schemer almost always keeps the dark meaning.

Though actually不過老實說, the shorter word scheme比較短的scheme這個字 is milder in British English在英式英文裡溫和多了 — a "pension scheme" or a "colour scheme"像「pension scheme」或「colour scheme」 has no dishonesty in it at all完全沒有不老實的意思。The person-word schemer但指人的schemer almost always keeps the dark meaning幾乎都還是帶著負面的意思。

(In computing, a Schemer can also mean someone who writes in the language Scheme. That is not this sense.)

In computing在電腦領域, a Schemer大寫的Schemer can also mean也可以指 someone who writes in the language Scheme用Scheme這個程式語言寫程式的人。That is not this sense（這不是這裡講的意思）。
