A convent is a community of monks, nuns, friars, or religious sisters, or the building used by the community. The term is particularly used in the Catholic Church, Lutheran churches, and the Anglican Communion. The word "convent" derives from the Latin word "conventus," meaning "to convene, to come together". In modern English usage, the term "convent" almost invariably refers to a community of women, while "monastery" and "friary" are used for communities of men. However, in historical usage, they are often interchangeable, with "convent" especially likely to be used for a friary.
According to Merriam-Webster, a convent is "a local community or house of a religious order or congregation, especially an establishment of nuns". Cambridge English Dictionary defines a convent as "a building in which nuns (= members of a female religious order) live". Dictionary.com defines a convent as "a community of persons devoted to religious life under a superior" or "a society or association of monks, friars, or nuns, now usually used of a society of nuns".
In summary, a convent is a religious community of women or the building used by the community. It is a place where nuns live and practice their religious beliefs.
