Nautch girls, also known as nachni or natya, were dancers who performed in India during the 19th and early 20th centuries. However, the term "nautch girl" became associated with exploitation and objectification of women, leading to its decline in usage. To avoid using this derogatory term, some alternative synonyms that can be used to describe these performers include "classical dancer," "courtesan," "traditional dancer," or "professional entertainer." These synonyms highlight the artistry and talent of these women, rather than solely objectifying them based on their profession. It's important to use appropriate and respectful language when referring to historical figures and their occupations.
