General terms:
* சதி செய்பவர் (Sathi seivavar): This literally translates to "one who does a conspiracy" and is the most direct translation.
* குற்றவாளி (Kuttavaali): This means "criminal" and could be used if the conspiracy is illegal.
* சதி காரர் (Sathi kaarar): This is more specific to someone who plans and carries out a conspiracy.
More specific terms:
* சதியாளர் (Sathiyaalar): This refers specifically to someone involved in a conspiracy, highlighting their role in the plot.
* கூட்டு சதி செய்பவர் (Koottu sathi seivavar): This literally translates to "one who does a conspiracy together" and is used when referring to multiple conspirators.
The best translation will depend on the specific context of the situation. For example, if you are talking about someone involved in a political conspiracy, "சதியாளர்" or "சதி காரர்" might be the most appropriate terms. However, if you are talking about someone involved in a criminal conspiracy, "குற்றவாளி" or "சதி செய்பவர்" might be better choices.
It's always a good idea to consider the nuances of the language and choose the word that best fits the specific situation.
