Ethical words are usually secondary lexemes, formed on the basis of other meanings: spatial, food, anatomical, color, etc. One of the language codes of folk ethics is social. The paper describes which social groups are ethically interpreted in Serbian and how ethical concepts are conceptualized on the basis of social names. There are three such social groups: the villager (‘prostak’), the provincial townsman (‘malogradjanin’) and the aristocrat (‘gospodin’). The names of the villager develop the meaning of rudeness, the names of the provincial townsman – self-interest and lack of spirituality, the names of the aristocrat – arrogance. Unlike Russian, Serbian social names did’t develop positive ethical meanings (cf. positive concept ‘интеллигентность’ in Russian).
