If you're talking about the act of borrowing:
* Lent: This means you are giving something to someone for a temporary period.
* Owned: This means you have full possession of something.
If you're talking about the state of being borrowed:
* Original: This means it is the authentic item, not a copy.
* Own: This means you possess it yourself.
Example:
* "I have a borrowed car" - the opposite could be "I have my own car."
* "I lent you my book" - the opposite could be "You borrowed my book."
It's important to consider the context to determine the most accurate opposite.
