Overview

The Romanization of Bulgarian converts Bulgarian Cyrillic letters into the Latin alphabet so that names, addresses and words can be read and used in languages written with Latin script. One widely referenced approach is the Streamlined System for the Romanization of Bulgarian developed by Lyubomir Ivanov in 1995 at the Institute of Mathematics and Informatics. This system is a practical, ASCII-friendly transliteration intended to balance ease of reading, typing and computer processing with a consistent letter-for-letter mapping. The term transliteration describes this sort of conversion, while the language involved is Bulgarian and its script the Cyrillic alphabet.

Characteristics

The Streamlined System aims to be simple and user-friendly. It generally uses single or paired Latin letters (such as "sh" or "ch") rather than diacritics, making it fit for contexts where ASCII characters are preferred. The method tries to keep a one-to-one relationship between Cyrillic and Latin characters so that readers can often reconstruct the original Bulgarian spelling.

History and development

Lyubomir Ivanov and colleagues at the Institute of Mathematics and Informatics proposed the Streamlined System in the mid-1990s. It emerged amid broader efforts to establish reliable transliteration practices for administrative use, mapping, and publishing. Over time, several institutions and publications adopted similar rules, while international standards bodies and other national schemes proposed alternative approaches emphasizing reversibility or phonetic fidelity.

Uses and examples

Practical applications include road signs, maps, databases, web content and personal names in travel documents. Because it avoids diacritics, the system is convenient for internet addresses and computer systems. Common examples of Romanized Bulgarian words readable to international users include:

  • България → Bulgaria
  • София → Sofia
  • Пловдив → Plovdiv
  • Червен бряг → Cherven bryag

Comparisons and notable facts

The Streamlined System is one of several methods. ISO-style transliteration standards emphasize exact reversibility and often use diacritics; phonetic transcription methods try to reflect pronunciation rather than spelling. The Streamlined approach is widely appreciated for its practicality and for producing Latin forms readily accepted in everyday international contexts.
