A quick definition of ORP:

ORP stands for Ordinary, Reasonable, and Prudent. This is the standard that is used in cases where someone is accused of being negligent. It means that a person should act in a way that an ordinary, reasonable, and prudent person would act in the same situation.

On a different note, an orphan is a child who has lost one or both parents. If a child has lost both parents, they are called a full orphan. If a child has lost one parent, they are called a half orphan. A child who has no parents or legal guardian is also considered an orphan.

Lastly, an orphan drug is a medication that is used to treat a rare disease or condition. These drugs are called orphan drugs because they are developed to treat a small number of people, and therefore, are not financially profitable for pharmaceutical companies to produce.
