A more thorough explanation:

Definition: An ejector is someone who removes or forces someone else out of a place or position.

For example, a landlord may be the ejector if they evict a tenant from their rental property. Another example is a security guard who ejects a disruptive person from a concert or event.

In legal terms, an ejector can also refer to the nominal defendant in an ejectment action. This is a legal process where someone is removed from a property they are occupying without legal right. The nominal defendant is the person who is sued in court, even though they may not have any actual connection to the property. This is a legal fiction used to resolve disputes over property ownership.

Overall, an ejector is someone who removes or dispossesses another person from a place or position, either through physical force or legal action.
