No, The House on Mango Street was not originally written in Spanish. The novel, authored by Sandra Cisneros, was first published in English in 1984. It tells the story of Esperanza Cordero, a young Latina girl growing up in a Chicago neighborhood, and explores themes of identity, cultural heritage, and the struggles of the Hispanic community.
While Cisneros has a deep connection to Spanish language and culture, especially as it relates to her own experiences, the English version of the book has been the one primarily recognized and celebrated in literary circles. However, the novel has been translated into Spanish and many other languages, broadening its reach and impact across different audiences.
