Definitions for "Fricative"
Produced by the friction or rustling of the breath, intonated or unintonated, through a narrow opening between two of the mouth organs; uttered through a close approach, but not with a complete closure, of the organs of articulation, and hence capable of being continued or prolonged; -- said of certain consonantal sounds, as f, v, s, z, etc.
A fricative consonant letter or sound. See Guide to Pronunciation, §§ 197-206, etc.
The term fricative is used to describe a sound which is articulated with almost a complete closure, but with just enough of an opening to create turbulence in the airflow. Examples of fricative sounds are /f/ as in fat, /v/ as in vat, /s/ as in sip, /z/ as in zip, and // as in ship.
