Etymology

Origin of nasal¹

1375–1425; late Middle English (adj.) < Medieval Latin *nāsālis, equivalent to Latin nās ( us ) nose + -ālis -al ¹

Origin of nasal²

First recorded in 1470–80; late Middle English, from Medieval Latin nāsāle, noun use of neuter of nāsālis (unattested) nasal ¹ ( def. ); replacing Middle English nasel, from Middle French, from Medieval Latin, as above

Explanation

Anything nasal relates to the nose, including a nasal voice that you can make by pinching your nose. Just as optical things relate to the eyes, nasal things relate to the nose. Your nostrils lead to your nasal passages, and if your septum (the middle part of your nose) needed to be repaired, it would require nasal surgery. Also, this word is commonly used to describe a kind of exaggerated, wheezy tone of voice that you can imitate by pinching your nose. Some people's voices are naturally nasal, like the singer Bob Dylan.
