Dionisio
Masculine · “Greek Dionysos”
The AD dating system was worked out by a monk in 525, and he got the date wrong. Dionysius Exiguus calculated the year of the Nativity a few years late, which is why Herod, who died in 4 BC, outlives the birth he is supposed to have threatened.

The story of Dionisio
Dionysius Exiguus, Dionysius the Humble, was a monk in Rome who was asked to extend the tables used for calculating Easter. Rather than continue numbering years from the reign of Diocletian, a persecutor, he numbered them from the incarnation, and the system spread through Bede's use of it in the eighth century. His arithmetic put the Nativity a few years too late by the standards of every subsequent reckoning, and there is no year zero, which is why centuries begin awkwardly. The name he carried belongs to the god of wine, which the Church absorbed along with the rest of the theophoric stock; Denis, Dennis, Dionisio and Dionysia all descend from it.

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
