Wiktionary:Ukrainian transliteration

Ukrainian text in Wiktionary is accompanied by transliterations according to the scholarly system of transliteration used in linguistics. The version here is as described in Daniels and Bright’s World’s Writing Systems, p. 702, with archaic letters borrowed from the Russian table, p. 351, and Old Slavic Alphabets table, p. 348.

Obsolete letters may appear in etymologies, attested words, and quotations. Letters ё, ъ, ы, ѣ, and э went out of use by the early 1920s. The Middle Ukrainian letters ѧ ѩ, ѫ, ѭ, ѯ, ѱ, ѳ, and ѡ went out of use before the 19th century.

Stress
Syllabic stress can be indicated by an acute accent (´) over the main component of the vowel:
 * Roman: Á, É, Jé, Ý, Í, Jí, Ó, Ú, Jú, Já, á, é, jé, ý, í, jí, ó, ú, jú, já
 * Cyrillic: А́, Е́, Є́, И́, І́, Ї́, О́, У́, Ю́, Я́, а́, е́, є́, и́, і́, ї́, о́, у́, ю́, я́

Variable stress can be indicated by an accent in each possible place: апо́стро́ф (apóstróf).

Background
Other common systems for Ukrainian are the Library of Congress system (ALA-LC), used in libraries and bibliographies, its simplified form found in the main text of many publications, the British Standard used in older British publications, BGN/PCGN in older atlases, and the Ukrainian National system, which has been adopted by the UN. Some of these are described in Appendix:Ukrainian alphabet.
