occlusive

This term describes a physical state of total blockage or closure. In medical contexts, it refers to materials or processes that seal off an area from the external environment, creating an airtight or watertight barrier to protect a wound or prevent contamination. In linguistics and dentistry, the word shifts toward the mechanics of contact. It describes the precise moment of closure, whether it is the meeting of teeth during a bite or the momentary cessation of airflow in the throat or lips to create specific speech sounds.
