Explanation

A secessionist is someone who wants to break away from a larger group. People who make plans to split from their government and form a new country are secessionists. Secessionist comes from secede, "formally withdraw from," and its Latin roots, which mean "go apart." A secessionist wants to make a break, almost always from their country.
