What type of articulation is represented by the sound /sh/?

The sound /sh/ is classified as a fricative because it is produced by forcing air through a narrow channel made by placing the tongue close to the roof of the mouth, which creates a turbulent airflow. This characteristic of creating friction during the articulation of the sound is what defines it as a fricative sound. When producing /sh/, the continuous airflow allows for a sustained sound, unlike a stop sound, which would block airflow momentarily. Other sound types, such as nasal sounds, involve airflow through the nose, while liquid sounds are characterized by their smoother and more continuous quality without the friction of fricatives. Thus, recognizing /sh/ as a fricative aligns with the specific manner of articulation involved in producing that sound.
