Ř
The grapheme Ř, ř (R with caron, example of Czech pronunciation: ) is a letter used in the alphabets of the Czech and Upper Sorbian languages. It was also used in proposed orthographies for the Silesian language. It has been used in academic transcriptions for rhotic sounds.

Usage
Czech
Ř is the 28th letter of the Czech alphabet. In the Czech language ř is used to denote , a raised alveolar non-sonorant trill. Its manner of articulation is similar to other alveolar trills but the tongue is raised; it is partially fricative. It is usually voiced but it also has a voiceless allophone occurring in the vicinity of voiceless consonants or at the end of a word.
In the oldest medieval texts, the sound of ř was simply spelled as r, then it was written using a variety of letter combinations, such as rs, rſ, rſſ, rz, and rzſ (compare oltars to modern oltář). According to Jan Gebauer (1894), the earliest known distinct appearance is in the place names and Orſechow in a charter or deed from 1237. In the early 15th century work De orthographia bohemica, attributed to Jan Hus, the letter ṙ is introduced. The dot diacritic above the letter gradually had various forms, which eventually became the modern ř. Its Polish equivalent is ⟨rz⟩, which represents a somewhat different sound.
Upper Sorbian
Ř is a letter in the Upper Sorbian alphabet. In the Upper Sorbian language it denotes the voiceless postalveolar fricative . The letter only occurs after p, t, and k; it originates from older r that had been devoiced by those sounds by the early 9th century, and became a sibilant in the following centuries. The letter does not appear in the orthography of Lower Sorbian.
Silesian
The letter is present in a proposed alphabet for Silesian, the , created in 2006. The alphabet was created with the goal of limiting the use of digraphs as much as possible, by replacing them with single characters. Ř had also been proposed in an orthography presented in 2001 by Piotr Kalinowski and Józef Kulisz, being used instead of the Polish digraph ⟨rz⟩ ; this was done with the intention of emphasizing the separateness of Silesian from Polish. The writing system was only used in a few short internet entries of both codifiers. The letter was also used in a project by the linguist , presented in 2008, which was meant to reflect the phonetic diversity of the entire Silesian-speaking region by assigning letters to sounds heard only in some areas; ř represented the fricative trill of Cieszyn Silesian, like in Czech. The system did not attract much interest and is known only from the text of her paper.
Romani
It is used by academics and activists to represent the Romani language's second rhotic retained in some dialects (which is also commonly spelled as ⟨rr⟩), variously pronounced as a long trill , a uvular trill , or a retroflex tap or approximant .
Kurdish
In some Latin-based scripts of Kurdish, it represents the voiced alveolar trill , as opposed to the alveolar tap represented by ⟨r⟩.
Americanist notation
In Americanist phonetic notation, ř has been used to represent a flap. This usage might come from William A. Smalley in Manual of Articulatory Phonetics (1963).
Berber
The letter is used in scholarly transcriptions of Riffian Berber. It represents a sound that comes from historical *l; in most Riffian dialects it is distinguished from r by its lack of influence on nearby vowels, however in some dialects this contrast is strengthened either by ř being trilled and r being a tap, or by ř being palatalized and r not being palatalized. Ř is a rhotic approximant or fricative in some dialects.
Hausa
In Paul Newman's transcription of Hausa (seen in A History of the Hausa Language), it is used to represent the trill, as opposed to the flap represented by r. The contrast between the two is marginal in the modern language, but the distinction is important for tracing the phonological history of Hausa.
IPA
Lowercase ř is an obsolete symbol of the International Phonetic Alphabet, used as of 1912 and 1926. It represented the apicoalveolar fricative trill (as in Czech). The symbol was replaced by ɼ, a long-legged r, which was rarely used for a few decades before being retired in 1989. The sound is now represented by .
Umbrian
In transliterations of the native alphabet of the extinct Umbrian language, ř is used to designate a sound of unknown quality, generally deriving from earlier intervocalic *d (and also from intervocalic *l that preceded a front vowel). The same sound was represented in the Latin alphabet by the sequence ⟨rs⟩.
