* In English language a word can mean many things, even unrelated. Here the phrase "Accounting entries" means "Journal entries". There is neither a "Book" nor "Journals". There is a database table that contains all accounting entries. "Accounting for [something]" means "how to record this in an accounting (bookkeeping) system". The button "make entries" in the documents means posting it (making accounting entries for this document). "A document" can be an invoice, for example. Things like "a document", "an employee", "a tax", etc are called "Entities".
