NASALITY Meaning and
Definition
-
Nasality refers to the quality or characteristic of a sound produced when airflow passes primarily through the nasal cavity, resulting in a distinctive nasal resonance or tone. It is a term commonly used in linguistics, phonetics, and speech pathology to describe the presence of nasalized speech sounds.
In terms of phonetics, nasality occurs when a speaker produces a sound by allowing air to pass through their nasal passages, in addition to the oral cavity. This happens when the velum, or the soft part of the roof of the mouth at the back, is lowered, allowing the air to flow into the nose and escape through the nostrils. This process is fundamental to producing nasal consonants like /n/, /m/, and /ŋ/, as well as nasal vowels found in certain languages.
Nasality can vary among individuals and is influenced by factors such as regional accent and speech disorders. Speakers with a nasal voice quality may be perceived as having a blocked or stuffy nose, although this is not always the case.
In the field of speech pathology, nasality is closely associated with disorders such as hypernasality and hyponasality. Hypernasality refers to excessive nasality, which may occur due to structural abnormalities or functional issues concerning the closure of the velopharyngeal port. Hyponasality, on the other hand, involves insufficient nasality when nasal sounds are replaced by oral sounds. Both conditions can significantly impact intelligibility and communication.

Etymology of NASALITY
The word "nasality" comes from the Latin word "nasus", meaning "nose". The Latin root "nasus" was combined with the suffix "-ity", which denotes a state or quality. Therefore, "nasality" refers to the quality or state of being nasal, specifically in terms of speech or sound production.
