The story of Konstantinos
Constantine legalized Christianity, called the Council of Nicaea and refounded Byzantium as Constantinople in 330. In the Greek Orthodox world he and his mother Helena are saints, and the name has been among the most-used Greek men's names ever since. Its everyday Greek forms are Kostas and Dinos. It reaches American records with Greek emigration, usually shortened at once.
Meaning
steadfast, constant
From Latin constans, standing firm, on stare, to stand; Constantinus is the diminutive. The same root gives English constant, and the sense is about remaining rather than about frequency.

The Hoyle test
Every popular name lives one long story — a climb, a peak, a slow settling back. Konstantinos's later chapters haven't been written yet, so we borrowed them: Hoyle climbed just as high around 1925, and its whole arc is on record. Line the two peaks up, and Hoyle's path sketches the road Konstantinos is walking now.

- Twelve letters and four syllables is a great deal for any American form.
- Americans will not attempt the full name and will use a short form from the start.
- Konstantinos, Constantine and Konstantin are all in use and look quite different.
