How to say it
Meaning in plain English
In plain English, a conspirator is a person involved in a plot. The plot may be criminal, political, fictional, or simply secretive, but the word usually suggests deliberate cooperation rather than one person acting alone.
Tone, context, and nuance
Conspirator is more specific than schemer because it usually involves more than one person. It is more serious than mischief-maker and less colorful than mountebank. In legal contexts, it can be very serious; in fiction, it is a useful word for intrigue.
Word origin
Conspirator comes from Latin roots meaning to breathe together. That older idea of acting in shared secrecy fits the modern sense of plotting with others.
