Ŭ

Ŭ or ŭ is a letter in the Belarusian language, when written in the 20th century form of the Belarusian Latin alphabet, and is also a letter in the Esperanto alphabet. The accent mark (diacritic) is known as a breve.

This letter should not be confused with u-caron, which is used to indicate u in the third tone of Chinese language pinyin. Compare Ǔ ǔ (caron) with Ŭ ŭ (breve).

Belarusian

The letter ŭ is called non-syllabic u (romanised: u nieskładovaje) in Belarusian because it resembles the vowel u but forms no syllables. It is an allophone of /v/ that forms the diphthongs aŭ, eŭ, oŭ and is equivalent to [u̯]. Its Cyrillic counterpart is ў. Sometimes (as in National Geographic atlases), the Cyrillic letter ў is Romanized as "w".

Esperanto

Ŭ represents a semivowel in the orthography of Esperanto, which is an international auxiliary language created in the late 19th century. As in Belarusian, Esperanto Ŭ is pronounced as a non-syllabic [u̯], primarily in the diphthongs aŭ and eŭ.

It is thought that ŭ was created by analogy with the Belarusian letter ў (Cyrillic u with breve), which was proposed by P.A. Bessonov in 1870.^{[citation needed]}

Ŭ may also be used for [w] in foreign names, such as Ŭaŝingtono for "Washington", although it usually is written with v (Vaŝintono). It is also used for [w] in onomatopoeias, as in ŭa! "waa!", and uniquely in one native lexical word, ŭo, which is the Esperanto name of the letter ŭ itself.

Other uses

It is also a letter in some philological transcriptions of Latin, denoting a short U. The McCune-Reischauer Romanization of Korean uses "ŭ" to signify the close back unrounded vowel in 으. It is also used in ISO 15919 to transcribe the Malayalam language's samvṛtōkāram.
