Nasal is an adjective that refers to something related to or involving the nose. It can describe characteristics or functions of the nose, as well as things associated with it.
In terms of anatomy, nasal refers to the structures, passages, or cavities located in or connected to the nose. For example, the nasal cavity is the hollow space within the nose that allows air to pass through when breathing. The nasal septum is the cartilaginous and bony partition that divides the nasal cavity into two separate nostrils.
Nasal can also pertain to sounds or speech produced through the nose. This may indicate a distinct quality in the pronunciation of certain consonant sounds, such as "m" or "n," where the air passes through the nasal cavity. For instance, when pronouncing the letter "m," it involves nasal air flow through the nose, compared to pronouncing the letter "p," which does not require nasal airflow.
Moreover, nasal can describe certain medical conditions involving the nose, such as nasal congestion, which refers to the blockage or stuffiness of the nasal passages due to swelling of the nasal tissues or excessive mucus production.
In summary, nasal refers to anything associated with the nose, including its anatomy, functions, sounds, speech, and various medical conditions.
