What does the name Trinity mean?
Trinity is the English name for the Christian doctrine of one God in three persons, Father, Son and Holy Spirit. The word comes from Latin trinitas, "threeness", from trinus, "threefold". Wiktionary notes its use as a girl's name since the 1970s, either from the English word or as a translation of the long-established Spanish name Trinidad. It rose further after the character Trinity in The Matrix (1999).
