(law) someone who owns (is legal possessor of) a business
"he is the owner of a chain of restaurants"
One who owns something.
"The owner of the lost dog was relieved to see him returned safely home."
In plain English: An owner is someone who legally possesses something and has full control over it.
"The new owner moved into the house yesterday."
Usage: An owner is the person or entity that holds legal title to property and has the right to use, sell, or dispose of it. You should refer to the individual with authority over an item as its owner rather than using this term for temporary possessors or caretakers.
The word owner is formed by adding the suffix -er to the verb own. It refers to a person who owns something, combining the root meaning of possession with an agentive ending to denote the possessor.
