Maven comes from Yiddish and is widely used in American English, particularly in business, tech, fashion, and media contexts. It carries a connotation of respected expertise and insider knowledge. In Brazil, the English term is sometimes borrowed in tech and fashion industries, but Portuguese equivalents like 'especialista' or 'perito' are more formal. The word suggests both knowledge and influence—a maven doesn't just know their field, they often guide others within it.
