What is the term for a person who is regularly given food as part of their accommodation?

The term for a person who is regularly given food as part of their accommodation is "Boarder." This designation applies to individuals who stay in someone else's home and pay for their living arrangements, which typically includes not only shelter but also meals.

In many boarding situations, the arrangement involves the boarder receiving regular meals as part of their agreement, which distinguishes them from other types of residents. For example, a guest might stay temporarily without compensation and may be expected to provide for their own meals. A resident may live in a place without necessarily having meals provided, particularly in apartment settings where living expenses cover only accommodation. An inmate, on the other hand, refers to someone who is confined in an institution such as a prison and is not typically associated with an accommodation arrangement characterized by a boarding agreement.

Thus, "Boarder" is the most accurate term to describe someone who receives food regularly as part of their accommodation arrangement.
