The word "Journal "has been derived from the French word "Jour". Jour means day. So, Journal means daily. Transactions are recorded daily in Journal. As soon as a transaction takes place its debit and credit aspects are analyzed and first of all recorded chronologically in a book together with its short description. This book is known as Journal. The most important function of Journal is to show the relationship between the two accounts connected with the transaction. Journal is also called the "Book of Original Entry" or "Day Book" because it keeps day-to-day record of transactions.
