masochist

The term 'masochist' is a modern formation, coined in 1886 by the German psychiatrist Richard von Krafft-Ebing. He derived it directly from the surname of Leopold von Sacher-Masoch, whose literary works prominently featured characters who found pleasure in submission and suffering. The suffix '-ist', of Greek origin via Latin and French, is a standard agent-noun ending used to denote a practitioner of a specific behavior or doctrine. Thus, the word's logic is eponymous: it literally means "a person characterized by the traits described by Masoch," transforming a proper name into a general psychological and behavioral category.

Structure: masoch (name) + ist (person who advocates/practices) - masoch: From the name of Leopold von Sacher-Masoch (1836–1895), an Austrian writer who described such tendencies in his novels. Origin: German (surname). - ist: A suffix forming agent nouns, denoting a person who practices or is concerned with something. Origin: French -iste, from Latin -ista, from Greek -ιστής (-istēs).
