Fricatives (or spirants) are consonants produced by forcing air through a narrow channel made by placing two articulators close together. These are the lower lip against the upper teeth in the case of , or the back of the tongue against the soft palate in the case of German , the final consonant of Bach. This turbulent airflow is called frication. A particular subset of fricatives are the sibilants (sometimes referred to as stridents). When forming a sibilant, one still is forcing air through a narrow channel, but in addition the tongue is curled lengthwise to direct the air over the edge of the teeth. English , , , and are examples of this.
