What is "nasal"?
The term "nasal" pertains to the structures and functions associated with the nose. This includes the external features such as the nostrils and nasal septum, as well as the internal components like the nasal passages and sinuses. The nasal cavity is responsible for various important functions, including filtering, warming, and humidifying the air we breathe. It also plays a crucial role in our sense of smell. The nasal mucosa, along with the presence of blood vessels and cilia, helps in these processes and serves as a protective barrier for the respiratory system.

What is a "nasal"?
A nasal is a type of consonant sound produced by allowing airflow to pass through the nose while the mouth is partially or completely closed. This occurs when the velum, the soft part of the roof of the mouth, is lowered, allowing air to escape through the nasal cavity. In English, examples of nasal consonants include "m" in "man," "n" in "nose," and "ng" in "sing." Nasal sounds are important in phonetics because they contribute to the variety of speech sounds and play a significant role in distinguishing words based on their pronunciation.
