Here are some examples:
* "Sola Scriptura" - This Latin phrase means "Scripture alone" and is a fundamental principle of Protestantism.
* "Proprietary solus" - This means that a product or service is owned and controlled exclusively by one company.
* "Solus Agreement" - This is a contract where one party agrees to only sell a specific product or service from another party.
However, "solus" is not commonly used in everyday English conversation.
