* Lack of Recognition: Since it's not in dictionaries, many people won't understand its meaning. It could be misconstrued or even sound awkward.
* Potential for Misinterpretation: The term "radical" itself carries strong connotations, often associated with extreme political views or actions. Using "radicalist" could unintentionally reinforce these negative perceptions.
* Alternatives Exist: Depending on your intended meaning, there are usually better alternatives. You could use:
* Radical: If you're referring to a person holding extreme views.
* Extremist: If you're describing someone with radical views who may use extreme methods.
* Revolutionary: If you're highlighting a desire for fundamental change.
* Activist: If you're emphasizing someone actively promoting a cause.
Example:
Instead of saying: "He was a radicalist who believed in overthrowing the government,"
You could say: "He was a radical who advocated for revolution."
Ultimately, it's about choosing the most accurate and appropriate term for your context.
