Our story of Marni
Ours, offered as ours. Names ending in a bare -i rather than -ie or -y were rare in English before the twentieth century and became a distinct fashion in the 1960s — Marni, Toni, Randi, Jodi, Traci. The ending reads as informal and modern to an English eye precisely because it is neither the old English -y nor the French -ie. It was a small, deliberate break with both.
Meaningscholars disagree
of the sea; or rejoice
Marina is from Latin marinus, of the sea. A Hebrew reading from a root meaning to rejoice is also given. Marnie may separately be a Scottish form of Marina or Margaret. None is established for this spelling.

The Darline test
Every popular name lives one long story — a climb, a peak, a slow settling back. Marni's later chapters haven't been written yet, so we borrowed them: Darline climbed just as high around 1933, and its whole arc is on record. Line the two peaks up, and Darline's path sketches the road Marni is walking now.
