From trinitas to Triniti
The story of Triniti
Tertullian, writing in Carthage, needed vocabulary for a doctrine that had none — and he built it, coining trinitas, substantia and persona in their theological senses. A great deal of the technical language of Western Christianity was invented by one man arguing in Latin. The word came into English use as a girl's name in the twentieth century and Triniti is a modern respelling.
Meaning
threeness
From Latin trinitas, a noun Tertullian appears to have coined from trinus, threefold, to name the doctrine. It is an abstract noun meaning the quality of being three, and it entered English through French.

Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method
