Trinity
Meaning
triad; the Trinity
The story
Trinity takes a Christian theological word and turns it into a personal name. The doctrine describes one God in three persons: Father, Son, and Holy Spirit. The English word comes through Latin trinitas, but Trinity itself did not become a familiar given name until the twentieth century. Its US curve is sharply modern. The name barely registers before the late twentieth century, rises in the 1990s, reaches its high point in the 2000s, and then eases through the 2010s and 2020s. The film character Trinity in The Matrix arrived near the beginning of that high period, but a chart alone cannot tell how many families chose the name for the movie, for faith, or simply for its sound. That distinction matters. Trinity's public associations are modern, while the idea named by the word is ancient. Each family decides which layer leads.
