Definition
Adjective:
- Tending to occlude: Describes something that has the property of closing, blocking, or obstructing a passage or opening.
Noun:
- A consonant produced by stopping the flow of air at some point and suddenly releasing it: In phonetics, a speech sound made by completely blocking the airflow in the vocal tract and then releasing it. This category includes sounds like /p/, /t/, /k/, /b/, /d/, and /g/.
Usage Examples
Adjective:

- An occlusive dressing is used to seal a wound from air and moisture. (The dressing has a sealing property.)
Noun:
- The sounds /p/ and /b/ are both bilabial occlusives. (These are consonants made by stopping air with the lips.)
- In English, occlusives are also called stop consonants or plosives. (These terms refer to the same type of sound.)
Advanced Usage
- In Phonetics: The term "occlusive" is often used interchangeably with "stop" or "plosive." However, some linguistic analyses distinguish "occlusive" as a broader category that includes both oral stops (plosives) and nasal stops (like /m/, /n/), where airflow is blocked in the mouth but continues through the nose.
- Linguists debate whether nasals should be classified as occlusives.
