The story of Constantinos
The Ottomans did not rename Constantinople. They used several names for the city — Konstantiniyye, Dersaadet, Islambol and others — and Konstantiniyye, which is simply the Arabic-Turkish form of the Greek name, was the official one on coins and documents for most of the empire's history. Istanbul existed alongside it in speech, derived from a Greek phrase meaning to the city, which is what Greeks called it when they were not naming it. The change to a single official name came only in the nineteen-twenties and thirties under the republic, with the post office eventually refusing mail addressed to Constantinople. So a Greek imperial name survived the conquest by four and a half centuries, in Turkish, on official paper.
Meaning
steadfast; constant
From the Latin adjective for standing firm, with the ending that made it a personal name. It became one of the commonest names in the Greek world through the emperor and the city, and Greek has kept the full Latin form where French, Italian and English all shortened it.

Fashion outlook
Constantinos sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.

- Four syllables is long for forms designed around shorter names.
- Konstantinos and Constantine are both recorded and the spelling will need giving.
- English speakers will stress it differently from Greek ones.
