In olden times refers to a period in the past, usually before the modern era. The term can be expressed in three different ways: AGO (3 letters), ONCE (4 letters), and ofyore (6 letters). AGO is used to refer to a time that has passed, ONCE is used to describe something that happened in the past, and ofyore is used to describe something that happened in the distant past. All three terms are used to refer to a time in the past that is no longer relevant.
