Voiced alveolar approximant

A voiced alveolar approximant is a type of consonantal sound used in some spoken languages. It is familiar to most English-speakers as the ⟨r⟩ sound in rose (though typically § postalveolar). The symbol in the International Phonetic Alphabet that represents it is ⟨ɹ⟩, a lowercase Latin letter ⟨r⟩ rotated 180 degrees.
