Fricative consonants are produced by forcing air through a narrow channel made by placing two articulators close together (e.g. the upper teeth and lower lip in the case of , or the back of the tongue and the soft palate, as in the case of German [x], 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 the air is directed over the sharp edge of the teeth. English [s], [z], [ʃ], and [ʒ] are examples of this.

See English language#Consonants for a table of fricatives in English.

Ubykh may be the language with the most fricatives, with 26. This number actually outstrips the number of all consonants in English (which has 24 consonants).
