The story of Sindy
Greek gods were addressed by dozens of epithets, most of them local, and a cult title usually names a place, a function or a story. Artemis is Kynthia from her birthplace on Delos, Ephesia at Ephesus, Agrotera the huntress, Orthia at Sparta, Brauronia at Brauron. Apollo is Delios from the same island, Pythios at Delphi, Lykeios of the wolves, Smintheus of the mice. The epithets are not decorations: a worshipper at Ephesus and one at Brauron were addressing goddesses with different rites, different images and arguably different identities, all called Artemis. Roman poets took the epithets up as elegant substitutes for the plain names, which is how Cynthia reached English poetry in the sixteenth century and then, by a long route through Lucinda and Cindy, an American birth certificate.

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
