Gemeinschaft (German pronunciation: [ɡəˈmaɪnʃaft]) and Gesellschaft ([ɡəˈzɛlʃaft]) (generally translated as "community and society") are categories which were used by the German sociologist Ferdinand Tönnies in order to categorize social ties into two dichotomous sociological types which define each other.
The Gemeinschaft–Gesellschaft dichotomy was proposed by Tönnies as a purely conceptual tool rather than as an ideal type in the way it was used by Max Weber to accentuate the key elements of a historic/social change. According to the dichotomy, social ties can be categorized, on one hand, as belonging to personal social interactions, and the roles, values, and beliefs based on such interactions (Gemeinschaft, German, commonly translated as "community"), or on the other hand as belonging to indirect interactions, impersonal roles, formal values, and beliefs based on such interactions (Gesellschaft, German, commonly translated as "society").
