# Oster

A settlement in Ukraine; local name Остер.

## English name

**Oster** — Current official Ukrainian name in national romanization (2010), adopted by BGN/PCGN in 2019; selected for English geographical use. Also matches BGN/PCGN Ukrainian romanization (1965). Also matches ISO 9:1995 character transliteration. Also matches ALA-LC Ukrainian romanization (2011 table).

Other forms in use:

- **Ostyor** — Russian-based spelling for matching older English geographical references; independent prose frequency unverified. Not a separate official renaming.
- **Gorodets** — Medieval fortress name printed in English history; refers to an earlier settlement site, not an unrestricted modern synonym.
- **Stary Oster** — Old Oster, the earlier settlement after destruction of the fortress; scope differs from the present city.
- **Starhorod** — Historical settlement name printed in English history; associated with the older site now called Starohorodka.
- **Остер** — Original Ukrainian spelling for local sources quoted or indexed in English.

## French name

**Oster** — Same as in English; used as the French locality heading.

Other forms in use:

- **Ostior** — Russian-derived spelling explicitly printed in French locality prose; retained for older French source matching, not the current preferred heading.
- **Gorodets** — Medieval fortress name explicitly printed in French history; the old site and modern city have different footprints.

## About

Oster is a small city where the Oster River meets the Desna in Chernihiv Oblast, Ukraine. Remains of a medieval church recall its role in the principality of Pereiaslav.

## Notes

The medieval fortress site and the later city are distinct historical footprints. The modern main follows Ukrainian Oster; Russian Остёр underlies French Ostior. Standard-derived forms support retrieval without implying English or French press adoption. Sources checked 2026-11-15: https://en.wikipedia.org/wiki/Oster ; https://fr.wikipedia.org/wiki/Oster.
