Zenanas refer to the women's quarters or harem in an Islamic household. The word has evolved over time and has synonyms such as seraglio, female quarters, and concubinage. It is often associated with the cultural and social norms of the past, with women being confined to the private quarters of the household. However, with changing times and cultural values, the use of the word is relatively rare in modern times. Synonyms for Zenanas may vary depending on the culture or region. However, the underlying premise remains the same - the confinement of women to a specific area within a household for religious, cultural, or social reasons.
