Wiktionary:Greek transliteration

These are the rules concerning transliteration in Greek entries.

• This table is intended as a guide for those unfamiliar with the Greek alphabet. There is another page covering Ancient Greek transliteration.

• The transliteration of Greek letters into Roman characters is not intended to provide a phonetic representation of a word. The correct place for that is under the Pronunciation heading.

• Equivalences have been sought amongst data produced by librarians and geographers, professional people who need to transliterate names: for use in library catalogues, in gazetteers and for the labelling of maps, places where a reproducible methodology is essential. Due to the nature of Greek spelling, transliteration is often irreversible.

• ISO 843 (1997, TR) was obtained from values shown at Eesti Keele Instituut (pdf file), other sources are shown at the foot of this page.
