ethnic group- is a category of people who identify with each other based on common ancestral, social, cultural or national experience. Unlike most other social groups, ethnicity is primarily an inherited status. Membership of an ethnic group tends to be defined by a shared cultural heritage, ancestry, origin myth, history, homeland, language and/or dialect, symbolic systems such as religion, mythology and ritual, cuisine, dressing style, art, and physical appearance. Ethnic groups, derived from the same historical founder population, often continue to speak related and share a similar gene pool. By way of language shift, acculturation, adoption and religious conversion, it is possible for some individuals or groups to leave one ethnic group and become part of another (except for ethnic groups emphasizing racial purity as a key membership criterion).

ethnic group types-

Archaeological, Biological, Social, Cultural, Linguistic

Giovanni Boccaccio-was an Italian writer, poet, correspondent of Petrarch, and an important Renaissance humanist. Boccaccio wrote a number of notable works, including The Decameron and On Famous Women. As a poet who wrote in the Italian vernacular, Boccaccio is particularly noted for his realistic dialogue, which differed from that of his contemporaries, medieval writers who usually followed formulaic models for character and plot.

Decameron- is a collection of novellas by the 14th-century Italian author Giovanni Boccaccio (1313–1375). The book is structured as a frame story containing 100 tales told by a group of seven young women and three young men sheltering in a secluded villa just outside Florence to escape the Black Death, which was afflicting the city. Boccaccio probably conceived the Decameron after the epidemic of 1348, and completed it by 1353. The various tales of love in The Decameronrange from the erotic to the tragic. Tales of wit, practical jokes, and life lessons contribute to the mosaic. In addition to its literary value and widespread influence (for example on Chaucer's The Canterbury Tales), it provides a document of life at the time. Written in the vernacular of the Florentine language, it is considered a masterpiece of classical early Italian prose.
