In accounting, a journal is a book where all non-cash financial transactions of a business / trust are recorded in chronological order. It's also known as the "book of original entry" because it's where transactions are first recorded. Journal entries are used to create the general ledger, which is then used to produce financial statements. 

A "Journal" is indeed considered a Book of Prime Entry (also called Book of Original Entry) because it's the primary place where business transactions are first recorded before being transferred to the ledger. All transactions are initially recorded chronologically in the journal, providing a detailed account of each transaction. This initial record serves as the foundation for all subsequent accounting processes.
