What Trinity means
Trinity means a group of three, or threefold. The Latin trinitas is an abstract noun coined to name the Christian doctrine, so the word was built for theology rather than borrowed into it.
Where Trinity comes from
Trinity is the Latin trinitas, threeness, from trinus, threefold. Tertullian coined it around 200 AD because Latin had no existing word for the doctrine he was arguing for, which makes it one of the few religious terms with a known inventor. It reached English through Old French as a word long before it was a name, and Trinity College, Trinity Sunday and Trinidad — named by Columbus on a Sunday — all carry it.
Trinity in use
Trinity is the clearest film effect we have measured, because it happened twice. American births sat flat through the 1990s — 365 in 1995, 497 in 1997, 557 in 1998 — then rose to 1,571 in 1999, the year The Matrix opened on 31 March, and to 4,386 in 2000, the first full year after release. That is roughly eight-fold in two years, and the split between a part-year and a full-year lift is exactly what a late-March release should produce. It then plateaued at 4,587 and 4,452 before rising again to 5,202 in 2003, the year of both sequels, and peaking at 5,729 in 2004. Two releases, two lifts, both dated — which is why we are willing to name the cause here and not on other spikes. It now ranks 428th in the United States on 734 births and 1162nd in England and Wales on 29, across 95,582 lifetime births.
