What is christening? How to use in English

The word "christening" has its origins in the Early Christian Church. In Latin, the verb "christiare" means "to anoint with chrism," which is a mixture of olive oil and balm used for consecrating objects or people. The term "christening" was later adopted into Old English as "christening," which referred specifically to the sacrament of baptism, where water is used to symbolize the person's spiritual rebirth. In Christian tradition, christening is the religious ritual of baptism, where the person being baptized is formally welcomed into the faith community. Over time, the term "christening" also took on the connotation of a celebration or ceremony held after the baptism, often with the giving of a nickname or gift to the newly baptized individual. Today, the term "christening" is commonly used to refer to this post-baptismal ceremony, which is often held in a church or by a priest.
