DEFINITION of 'Baptism by Fire'. A phrase originating from Europe that describes an employee that is learning something the hard way, like being immersed in their field of employment. Baptism by fire has its roots in battle terminology, describing a soldier's first time in battle. Next Up.
That meaning has largely gone out of use and the meaning most often used now is of a soldier's first experience of battle. 'Baptism' because battle is new to him and 'fire' from the firing of guns, that is, he is 'under fire'. The connection between the earlier religious meaning and the later military meaning isn't clear. It is quite possible that the two are independent of each other.
