What does defectionist mean?
A defectionist is a person who defects — that is, who abandons one political party, organization, cause, or set of allegiances in favor of another — or who supports or advocates doing so. The term is used almost exclusively in political and organizational contexts, describing legislators who cross party lines, members of movements who break away, or supporters who urge others to abandon a leader or cause. Because it implies a breach of loyalty, it generally carries a pejorative connotation, often deployed by those left behind to characterize the departing party as disloyal or opportunistic. The word is considerably less common than its close relative 'defector', which refers specifically to someone who has completed an act of defection; 'defectionist' can also suggest an inclination toward defection rather than a single completed act. It derives from the Latin 'defectio', meaning a desertion or revolt, itself formed from 'deficere', meaning to fail or fall away.

Etymology of defectionist
Defectionist is formed from 'defection' plus the agentive suffix '-ist', denoting a person associated with an action or doctrine. 'Defection' comes from the Latin 'defectio', meaning desertion or revolt, derived from the verb 'deficere' (to fail, to desert, literally to 'do less' or 'fall away'), composed of 'de-' (away) and 'facere' (to do). This same Latin root gives English words such as 'defective', 'deficiency', and 'deficit'.
