owner
An "owner" is a person or entity that possesses something, such as property, a business, or a pet. Ownership implies legal rights, allowing the owner to use, manage, and transfer the item as they see fit. For example, a homeowner has the right to live in and modify their house.
In a business context, an owner may be an individual or a group, like a partnership or a corporation. They are responsible for the operations and decisions of the business, and they typically receive profits generated by it. An owner can also be someone who adopts a pet, taking on the responsibility for its care and well-being.
