Uvular Trill

The uvular trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʀ⟩, a small capital ar. This consonant is one of several collectively called guttural R.

Within Europe, the uvular trill seems to have originated in Standard French around the seventeenth century, spreading to standard varieties of German, Danish, Portuguese as well as in parts of Dutch, Norwegian and Swedish; it is also present in other areas of Europe, but it is not clear if such pronunciations are due to French influence. In most cases, varieties have shifted this to a voiced uvular fricative . See guttural R for more information.
