Domestic worker in the context of "Pulcinella"

A household consists of one or more persons who live in the same dwelling. It may be of a single family or another type of person group. The household is the basic unit of analysis in many social, microeconomic and government models, and is important to economics and inheritance.

Household models include families, blended families, shared housing, group homes, boarding houses, houses of multiple occupancy (UK), and single room occupancy (US). In feudal societies, the royal household and medieval households of the wealthy included servants and other retainers.

A cleaner, cleanser or cleaning operative is a type of industrial or domestic worker who is tasked with cleaning a space. A janitor (Scotland, United States and Canada), also known as a custodian, Facility Operator, porter or caretaker, is a person who cleans and might also carry out maintenance and security duties. A similar position, but usually with more managerial duties and not including cleaning, is occupied by building superintendents in the United States and Canada and by site managers in schools in the United Kingdom.

According to the Cambridge English dictionary a "cleaner" is "a person whose job is to clean houses, offices, public places, etc.:"; the Collins dictionary states that: "A cleaner is someone who is employed to clean the rooms and furniture inside a building." However, a cleaner does not always have to be employed and perform work for pay, such as in the case of volunteer work or community service. "Cleaner" may also refer to cleaning agents e.g. oven cleaner, or devices used for cleaning, e.g. vacuum cleaner.

A page or page boy is traditionally a young male attendant or servant, but may also have been a messenger in the service of a nobleman.

During wedding ceremonies, a page boy is often used as a symbolic attendant to carry the rings.

A lady-in-waiting (alternatively written lady in waiting) or court lady is a female personal assistant at a court, attending on a royal woman or a high-ranking noblewoman. Historically, in Europe, a lady-in-waiting was often a noblewoman but of lower rank than the woman to whom she attended. Although she may either have received a retainer or may not have received compensation for the service she rendered, a lady-in-waiting was considered more of a secretary, courtier, or companion to her mistress than a servant.

In some other parts of the world, the lady-in-waiting, often referred to as palace woman, was in practice a servant or a slave rather than a high-ranking woman, but still had about the same tasks, functioning as companion and secretary to her mistress. In courts where polygamy was practiced, a court lady might have been formally available to the monarch for sexual services, and she could become his wife, consort, courtesan, or concubine.

A eunuch (/ˈjuː.nək/ YOO-nək, Ancient Greek: εὐνοῦχος) is a boy or man who has been castrated. Throughout history, castration often served a specific social function. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 2nd millennium BC. Over the millennia since, they have performed a wide variety of functions in many different cultures: courtiers or equivalent domestics, for espionage or clandestine operations, castrato singers, concubines or sexual partners, religious specialists, soldiers, royal guards, government officials, and guardians of women or harem servants.

Eunuchs would usually be servants or slaves who had been castrated to make them less threatening servants of a royal court where physical access to the ruler could wield great influence. Seemingly lowly domestic functions—such as making the ruler's bed, bathing him, cutting his hair, carrying him in his litter, or even relaying messages—could, in theory, give a eunuch "the ruler's ear" and impart de facto power to the formally humble but trusted servant.

Housekeeping is the management and routine support activities of running and maintaining an organized physical institution occupied or used by people, like a house, ship, hospital or factory, such as cleaning, tidying/organizing, cooking, shopping, and bill payment. These tasks may be performed by members of the household, or by persons hired for the purpose. This is a more broad role than a cleaner, who is focused only on the cleaning aspect. The term is also used to refer to the money allocated for such use. By extension, it may also refer to an office or a corporation, as well as the maintenance of computer storage systems.

The basic concept can be divided into domestic housekeeping, for private households, and institutional housekeeping for commercial and other institutions providing shelter or lodging, such as hotels, resorts, inns, boarding houses, dormitories, hospitals and prisons. There are related concepts in industry known as workplace housekeeping and Industrial housekeeping, which are part of occupational health and safety processes.

In ancient Rome, the domus (pl.: domūs, genitive: domūs or domī) was the type of town house occupied by the upper classes and some wealthy freedmen during the Republican and Imperial eras. It was found in almost all the major cities throughout the Roman territories. The modern English word domestic comes from Latin domesticus, which is derived from the word domus. Along with a domus in the city, many of the richest families of ancient Rome also owned a separate country house known as a villa. Many chose to live primarily, or even exclusively, in their villas; these homes were generally much grander in scale and on larger acres of land due to more space outside the walled and fortified city.

The elite classes of Roman society constructed their residences with elaborate marble decorations, inlaid marble paneling, door jambs and columns, as well as expensive paintings and frescoes. Many poor and lower-middle-class Romans lived in crowded, dirty and mostly rundown rental apartments, known as insulae. These multi-level apartment blocks were built as high and tightly together as possible and held far less status and convenience than the private homes of the prosperous.

A valet or varlet is a male servant who serves as personal attendant to his employer. In the Middle Ages and Ancien Régime, valet de chambre was a role for junior courtiers and specialists such as artists in a royal court, but the term "valet" by itself most often refers to a normal servant responsible for the clothes and personal belongings of an employer, and making minor arrangements. In the United States, the term most often refers to a parking valet, and the role is often confused with a butler.
