sitter

The word "sitter" is quite flexible, moving from the home to the art studio and even to the sports field. Most commonly, it refers to a babysitter, the person trusted to care for children while the parents are away. From there, the idea extends naturally to house-sitters and pet-sitters, people who stay with or look after a home or animal for a period of time. In these uses, the word suggests care, responsibility, and a temporary duty.

Beyond caregiving, "sitter" also has an established use in art. An artist's sitter is the person who poses for a painting, drawing, photograph, or sculpture. This meaning often carries the idea of staying still and holding a position, which is why an impatient or restless person may be described as a difficult sitter.

In a more literal sense, a sitter can simply mean someone who is seated. This use exists, but it is less central than the childcare and art meanings. When it appears, it usually just describes a person's position rather than a special role.

In British English, especially in soccer, a "sitter" can also mean an extremely easy chance, usually one that should have been scored. In that sense, the word is metaphorical: the opportunity seems to be waiting there, simple and ready to be taken.

So the word can point to a trusted caregiver, a person posing for an artist, someone who is seated, or even an easy scoring chance. The different meanings are linked by the basic idea of staying in place or being there for a particular purpose.
