What is orphan? How to use in English

The word "orphan" comes from the Greek phrase "orphanos," which means "son without a father." In ancient Greece, orphans were typically the sons of soldiers who had been killed in battle, and the term referred specifically to those who had lost their father in battle. Over time, the meaning of the word expanded to include children who had lost both parents, regardless of the circumstances. The Greek word "orphanos" is derived from the verb "orphnein," which means "to bereave or leave without a father." The Latin word "orphanus," which is closely related to the Greek word, was later borrowed into Middle English as "orphan." The modern English word "orphan" has retained the original meaning of a child who has lost one or both parents, but its scope has expanded to include a broader range of meanings and connotations.
