Trill consonant

A trill consonant is a consonant that is made by vibrating an articulator, or hitting it many times against something else. For example, the <rr> in the Spanish word "perro" is an alveolar trill, commonly known as a rolled r, where the tongue is hit many times against the alveolar ridge, or the place just behind the teeth. This vibration is caused by a flow of air.

There are three trill consonants in the International Phonetic Alphabet. These are:

 - alveolar trill
 - bilabial trill, where the lips are trilled.
 - uvular trill, where the uvula is trilled.
