Dictionaries of languages like English and German sometimes use the symbol ⟨r⟩. They have rhotic consonants that are not an alveolar trill. This is because typing the letter r is easier.

In many Indo-European languages, this sound is sometimes an allophone of the alveolar tap [ɾ]. This happens especially in unstressed syllables. Some languages like Catalan, Spanish, Albanian and some Portuguese treat these as two different sounds.

Features

• The airstream mechanism is pulmonic. This means that this sound is produced by pushing air solely with the lungs and diaphragm, as in most sounds.
• The phonation is voiced. This means that the vocal cords vibrate while the sound is being pronounced.
• The place of articulation (where the sound is produced) is alveolar. This means that this sound is produced with the tip of the tongue (apical) or the blade of the tongue at the alveolar ridge (laminal).
• The manner of articulation (how the sound is produced) is trill. This means that this sound is produced by directing air over the articulator so that it vibrates.
