A shut-in is someone who is ill or whose body will not let them leave the house easily. They are not staying in for fun. Neighbours might bring food to a shut-in; a nurse might visit. It can also be used as a description: a shut-in life, a shut-in winter. Though actually, people now sometimes stretch it to anyone who almost never goes out — a very private person, someone who lives on a screen — and that stretch can sound , as if choosing to stay home were the same as being trapped by illness. The older, kinder meaning is about not being able to go out. That is the one to learn first.
