the term 'welfare-state' is a 20th-century compound that merges two distinct concepts. 'welfare' originates from old english, combining 'wel' (well) and 'faran' (to go or fare), evolving to signify prosperity and well-being. 'state' derives from latin status, indicating a standing or condition, which came to denote a sovereign political entity. the compound logically describes a political system where the state assumes primary responsibility for the social and economic welfare of its citizens, a concept that crystallized in post-war western democracies.

Structure: welfare + state welfare (from middle english, from the old english phrase wel faran meaning 'to fare well', functioning as a noun meaning 'well-being'); state (from latin status meaning 'condition, position', functioning as a noun meaning 'a politically organized body of people')
