Here's why:
* Velar: This refers to the place of articulation. The back of the tongue (velum) is raised towards the soft palate to create the sound.
* Nasal: This refers to the manner of articulation. Air escapes through the nose, not the mouth, during the production of the sound.
This sound is represented by the letters "ng" in the English alphabet, but it's important to note that it is a single sound, not a combination of two.
